    Added: java/src/org/apache/xalan/xsltc ProcessorVersion.java
    Committer's log entry: new class to version xsltc software

  • Committed by jkesselm@apache.org on 12/05/2001
    Modified: java/src/org/apache/xml/dtm/ref/sax2dtm SAX2DTM.java
    Committer's log entry: Additional debugging printouts, added while analysing Bugzilla 5272 but generally useful. No functional change, and should be optimized away when DEBUG is set false.

  • Committed by jkesselm@apache.org on 12/10/2001
    Modified: java/src/org/apache/xalan/xslt Process.java
    Committer's log entry: Removed the "magic" default which causes us to switch into incremental processing mode whenever we were writing to Standard Output (ie, -OUT had not been specified). If you want incremental processing, please use the (relatively new) -INCREMENTAL switch to explicitly request it. (The automatic switchover was causing some confusion when testing against Xerces2. )

  • Committed by jkesselm@apache.org on 12/10/2001
    Modified: java/src/org/apache/xml/dtm/ref DTMDefaultBase.java DTMManagerDefault.java
    Committer's log entry: Efficiency improvement to the new DTM "overflow addressing" scheme. In some tests, this one alteration shaved about 30% off the runtime.

  • Committed by jkesselm@apache.org on 12/11/2001
    Modified: java/src/org/apache/xpath CachedXPathAPI.java XPathContext.java
    Committer's log entry: Changes requested by the xml-security group: 1) Provide something a constructor that allows sharing the XPathContext object between CachedXPathAPI objects 2) Add getXPathContext(). I'm just a bit nervious about this method, but they assure us they need it and the field isn't private. We may need to discus this one further. 3) Make the XPathContext's m_dtmManager member protected rather than private, so their subclass can get to it. We may want to work with them to understand why they're accessing this directly and whether there's a better solution.

  • Committed by jkesselm@apache.org on 12/13/2001
    Modified: java/src/org/apache/xml/dtm/ref IncrementalSAXSource_Xerces.java
    Committer's log entry: Bugzilla5272 patch suggested by Sandy Gao. This startup sequence for incremental SAX parsing under Xerces2 really is excessively complicated and excessively fragile as a result. Not to mention being underdocumented. We really need to push the Xerces folks to provide a simple incremental SAX API, similar to that in the Xerces1incremental prototype.

  • Committed by jkesselm@apache.org on 12/13/2001
    Modified: java/src/org/apache/xml/dtm/ref/sax2dtm SAX2DTM.java
    Committer's log entry: Part 1 of 2: Reducing initial space requirements of a DTM. This may involve a slight performance hit, but should help stylesheets which generate a lot of Result Tree Fragment. Part 2 of this change will be checked in after I resolve a bug in whitespace normalization. Note that a better long-term answer will be to reduce the number of DTMs tied up as RTFs, by doing a better job of discarding or reusing them when we're done with them. There are some issues regarding exactly what their lifetimes will be when assigned to variables, especially when one variable is used to build another, which we need to address before we can make that change.

  • Committed by jkesselm@apache.org on 12/13/2001
    Modified: java/src/org/apache/xml/dtm/ref/sax2dtm SAX2DTM.java
    Committer's log entry: Part 2a of 2: Reducing initial space requirements of a DTM. This may involve a slight performance hit in some circumstances due to smaller and more complex subdivision of FastStringBuffers,, but should help stylesheets which generate a lot of Result Tree Fragments. Note that a better long-term answer will be to reduce the number of DTMs tied up as RTFs

  • Committed by jkesselm@apache.org on 12/13/2001
    Modified: java/src/org/apache/xml/utils FastStringBuffer.java
    Committer's log entry: Part 2b of 2: Reducing initial space requirements of a DTM. This may involve a slight performance hit in some circumstances due to smaller and more complex subdivision of FastStringBuffers,, but should help stylesheets which generate a lot of Result Tree Fragments. (Leveraging FSB's features more strongly exposed a bug in whitespace normalization, which I've fixed.) Note that a better long-term answer will be to reduce the number of DTMs tied up as RTFs

  • Committed by jkesselm@apache.org on 12/14/2001
    Modified: java/src/org/apache/xml/utils AttList.java
    Committer's log entry: Two goofs: Forgetting to use the namespace-aware DOM call, and forgetting to check for a returned null before dereferencing. How long has _that_ been lurking in the undergrowth?!

  • Committed by jkesselm@apache.org on 12/14/2001
    Modified: java/src/org/apache/xml/utils SuballocatedIntVector.java
    Committer's log entry: Finally following up on an old hunch, I switched from /% addressing to shift-and-mask. Big improvement!

  • Committed by jkesselm@apache.org on 12/14/2001
    Modified: java/src/org/apache/xml/dtm/ref/dom2dtm DOM2DTM.java
    Committer's log entry: Performance improvements; Some changes to better leverage the DOM's existing code, others to avoid some call-and-return overhead. Combined with other recent changes, we've now got a significant speedup over D14 on some tests. We may want to drop the scheduled December 17th 2.2 release and instead bring 2.2 out on 1/14 (which is when we'd planned 2.3) with performance gains and Xerces2 support.

  • Committed by jkesselm@apache.org on 12/18/2001
    Modified: java/src/org/apache/xml/dtm/ref DTMDefaultBase.java java/src/org/apache/xml/dtm/ref/dom2dtm DOM2DTM.java DOM2DTMdefaultNamespaceDeclarationNode.java
    Committer's log entry: A few more subtle performance tweaks, and an actual bug.

  • Committed by curcuru@apache.org on 12/20/2001
    Added: java/src/org/apache/xml/utils ListingErrorHandler.java
    Committer's log entry: Alternate ErrorHandler/ErrorListener implementation that allows configuration and prints errors out similarly to javac

  • Committed by curcuru@apache.org on 01/13/2002
    Modified: java/src/org/apache/xml/utils SystemIDResolver.java
    Committer's log entry: Fix Bugzilla#5701: incorrect resolution of certain kinds of absolute file: URIs Note: This definitely seems to be more correct in terms of resolving URIs vis-a-vis RFC 2396 than it used to be. The only user case which might now fail where it used to work is a user that supplies an incorrect 'file:subdir/blah' that they intended to be a relative URI (technically it is an absolute URI no matter which way you look at it); this might lead to a change in behavior in this particular case, although the behavior before was incorrect. The major risk factor could be if there are other parts of Xalan code that rely on the previously incorrect behavior, but I can't find any, and the whole test suite runs and passes normally.

  • Committed by curcuru@apache.org on 01/14/2002
    Modified: java/src/org/apache/xalan/xslt Process.java
    Committer's log entry: Fix Bugzilla#4678 and Bugzilla#5533: call setSystemId on StreamResult in Process command line class; ignored if using System.out This should enable the redirect extension to properly put it's redirected output in a location relative to the output if possible; previously it always put redirected output relative to the input since it never had the systemId of where the output should be

NoteThis release includes no updates of the compatibility source code (now deprecated).

Changes for Xalan-Java 2.2.D14
 

Xalan-Java 2.2.D14 is intended to be the final release in the current series of Developer releases incorporating the DTM. We believe Xalan with the DTM has reached a level of stability that warrants a standard "User" release. Accordingly, we plan to release Xalan-Java 2.2 soon.

Xalan-Java 2.2.D14 also includes a new CachedXPathAPI class that provides an enhanced alternative to the XPath convenience methods in XPathAPI.

Beginning with 2.2.D12, xalan.jar contains just the Xalan-Java implementation. The source files for the SAX level 2, DOM 2, and JAXP 1.1 interfaces are pulled from the xml-commons repository (xml-commons/java/external/src), and are built as xml-apis.jar. These interfaces are shared by a number of tools, so placing them in their own jar simplifies coordination and reduces the risk of duplication. To run Xalan-Java, you must add xml-apis.jar to your classpath. See Setting up the system class path.

Core (Non-XSLTC) source code updates:

  • Committed by jkesselm@apache.org on 11/12/2001
    Modified: java/src/org/apache/xml/dtm/ref/dom2dtm DOM2DTM.java
    Committer's log entry: Reorder slightly and add test to not synthesize xmlns:xsl declaration if one was already present on the DOM's root element.

  • Committed by jkesselm@apache.org on 11/12/2001

  • Committed by jkesselm@apache.org on 11/12/2001
    Modified: java/src/org/apache/xalan/processor XSLProcessorVersion.java

  • Committed by jkesselm@apache.org on 11/15/2001
    Modified: java/src/org/apache/xml/dtm/ref DTMNodeProxy.java
    Committer's log entry: Bugzilla4842: Expand the proxy layer to support more of the DOM API.

  • Committed by jkesselm@apache.org on 11/15/2001
    Modified: java/src/org/apache/xml/dtm/ref/dom2dtm DOM2DTM.java
    Committer's log entry: Namespace decls are themselves not namespace-aware, in the Namespaces 1.0 REC. Use the qname.Grumble.

  • Committed by jkesselm@apache.org on 11/20/2001
    Modified: java/src/org/apache/xml/dtm/ref/dom2dtm DOM2DTM.java
    Committer's log entry: "Tupograflica eror". Sorry 'bout that!

  • Committed by jkesselm@apache.org on 11/26/2001
    Modified: java/src/org/apache/xml/dtm/ref/dom2dtm DOM2DTM.java
    Committer's log entry: Sigh. The XML Namespaces spec it itself imperfectly namespace-aware. While there's a plan to fix that, it's safer for now if we test the QName when looking for explicit instances of xmlns:xml in the source document.

  • Committed by jkesselm@apache.org on 11/26/2001
    Modified: java/src/org/apache/xalan/lib/sql DTMDocument.java java/src/org/apache/xalan/templates ElemApplyTemplates.java java/src/org/apache/xalan/xslt Process.java java/src/org/apache/xml/dtm DTMManager.java java/src/org/apache/xml/dtm/ref DTMDefaultBase.java DTMDefaultBaseIterators.java DTMDefaultBaseTraversers.java DTMManagerDefault.java java/src/org/apache/xml/dtm/ref/dom2dtm DOM2DTM.java java/src/org/apache/xml/dtm/ref/sax2dtm SAX2DTM.java
    Committer's log entry: Another fairly large change in the DTM architexture (sic).... We've changed DTM's internal behavior so it can now assign more than one "DTM ID" to a single document, cascading from one ID to the next. This means that the size of a single DTM is no longer limited by the bits available in the low part of the DTM Node Handle. This means we can support larger documents. That has allowed us to reduce the number of bits reserved for that portion of the node addresing scheme... which in turn has increased the number of bits available for use in the DTM ID. This means we can now have many more documents active at once. The trade-off is that huge documents will require more than one DTM ID and thus cut into the number of documents, But since we now have 16 bits of DTM ID space, I don't think we're really likely to run into both limits at once. And the changes are essentially limited to the DTM layer; the rest of Xalan should be unaffected. In the process of making this change, I've also encapsulated the conversions between DTM API node handles and DTMDefaultBase's internal node indices. That should be safer all 'round. NOTE: One side effect of this change is that the strings generated by the key() function have changed again. I've updated the IDKEY testcases to reflect this. Smoketest is currently passing everything except axes109 and the API's TraceListenerTest . But I believe those failures are due to a glitch in my test directory since they also happen when I run the D13 code there, whereas D13 runs fine in the directory where I built it. I'm going to assume that "same result is no new bug" for now.

  • Committed by jkesselm@apache.org on 11/26/2001
    Modified: java/src/org/apache/xml/dtm/ref DTMDefaultBaseTraversers.java
    Committer's log entry: Found the glitch causing the axes108 bug -- exptype/type.

  • Committed by jkesselm@apache.org on 11/27/2001
    Modified: java/src/org/apache/xalan/xslt Process.java
    Committer's log entry: Added option to set the recursion limit (which we're having trouble with right now; the code that supported it seems to be disabled...) and selfdoc for this and a few other newer options.

  • Committed by sboag@apache.org on 11/28/2001
    Modified: java/src/org/apache/xalan/transformer ResultTreeHandler.java
    Committer's log entry: Catch exceptions from the output content handler in flush(), and throw a SAXParseException with line numbers filled in. If we don't do this, and the exception is a RuntimeException, good line numbers of where the exception occured in the stylesheet won't get reported. I tried just catching RuntimeException, but for whatever reason it didn't seem to catch. Fix for Christina's DOMException error problem.

  • Committed by jkesselm@apache.org on 11/29/2001
    Modified: java/src/org/apache/xml/dtm/ref/dom2dtm DOM2DTM.java
    Added: java/src/org/apache/xml/dtm/ref/dom2dtm DOM2DTMdefaultNamespaceDeclarationNode.java
    Committer's log entry: Moved default namespace declaration node object out of its "inner class" status, since I think I want to perform an instanceof test on it.

  • Committed by jkesselm@apache.org on 11/29/2001
    Modified: java/src/org/apache/xml/dtm/ref DTMDefaultBase.java DTMManagerDefault.java java/src/org/apache/xml/dtm/ref/dom2dtm DOM2DTM.java java/src/org/apache/xpath XPathAPI.java
    Added: java/src/org/apache/xpath CachedXPathAPI.java
    Committer's log entry: Bugzilla 4336 -- fix for presenting symptom (since the implicit xml: declaration pseudo-DOM node is resynthesized in each DTM, find the _corresponding_ node), and a first draft of CachedXPathAPI which should be a fix for the larger symptom (XPathAPI creates a new DTM every time, which is potentially very ugly for applications that want to run XPaths repeatedly on a single document). Also caught and fixed another node-handle/node-identity confusion. The fact that DTM.get...() allowed us to be sloppy about that distinction in the past means there may still be a few others lurking in the code. Ye gods, I _wish_ Java had typedef!

  • Committed by jkesselm@apache.org on 11/29/2001
    Modified: java/src/org/apache/xml/dtm/ref DTMNodeProxy.java
    Committer's log entry: Minor tweaks

  • Committed by curcuru@apache.org on 11/29/2001
    Modified: java/src/org/apache/xalan/lib Redirect.java
    Committer's log entry: Patch to enable optional 'append' attribute on redirect:open and redirect:write elements to append to file; note that behavior may not be what you expect when using xml output, since the xml decl will currently be output *each* time you newly write to the file Submitted by: jpvdm@iafrica.com

  • Committed by jkesselm@apache.org on 11/29/2001
    Modified: java/src/org/apache/xml/dtm/ref DTMNodeProxy.java
    Committer's log entry: Implement getDocumentElement. If the DTM doesn't represent a wellformed Document, this call is undefined and throws an exception... which isn't DOMlike but that's a non-DOMlike situation.

NoteThis release includes no updates of the compatibility source code (now deprecated).

Changes for Xalan-Java 2.2.D12 and 2.2.D13
 

Xalan-Java 2.2.D13 is intended to be the final release in the current series of Developer releases incorporating the DTM. We believe Xalan with the DTM has reached a level of stability that warrants a standard "User" release. Accordingly, we plan to release Xalan-Java 2.2 soon.

Beginning with this release, xalan.jar contains just the Xalan-Java implementation. The source files for the SAX level 2, DOM 2, and JAXP 1.1 interfaces are pulled from the xml-commons repository (xml-commons/java/external/src), and are built as xml-apis.jar. These interfaces are shared by a number of tools, so placing them in their own jar simplifies coordination and reduces the risk of duplication. To run Xalan-Java, you must add xml-apis.jar to your classpath. See Setting up the system class path.

Beginning with this release, we are placing two distribution files in the xalan-j distribution directory: a binary distribution file, which includes everything needed to run Xalan-Java and build applications, and a source distribution. For more information, see Downloading what you need.

This release also includes ValidateXMLInput, a sample that illustrates how you can verify that the XML input you are transforming adheres to its document type. It is in the samples/validate subdirectory along with a Validate utility that you can use to validate XML files without performing a transformation.

    Committer's log entry: Avoid overgenerality of isDigits Combine most character tests into a single switch for performance Reject values with embedded (as opposed to leading/trailing) whitespace. Note that this is "more correct:" than the old solution of calling Java's toDouble, since (I think) XSLT doesn't officially accept leading + or scientific notation. If folks want to accept those notations, an extension function specifically for that purpose seems the simplest/safest/most-portable solution.

    Committer's log entry: Added fix for bug reported by Myriam for match="//x/a" patterns. On the second "/" on "//", the parser wasn't swallowing the token, which caused the "x" pattern to be ancestor instead of parent. If you don't have this fix, it will cause 'a' to be matched when it has any ancestor that is 'x'. This fix should be localized to only match patterns. The reason this probably wasn't reported before, is because "//" at the head of a match pattern is pretty useless, "x/a" being equivelent.

    Committer's log entry: Leverage Xerces-2 incremental parsing feature, when possible, Making this compile _and_ run under both the old and new versions of the parser involves a lot of reflection... especially since Xerces-2 no longer provides a way to directly request incremental delivery of SAX events; we now have to assemble that concept ourselves, using XNI components. Note that if you pass an existing Xerces-2 SAXParser into the IncrementalSAXSource_Xerces wrapper, there is currently no way for us to access its incremental controls. In that case, we are forced to fall back on the _Filter solution and coroutines.

    Modified: java/src/org/apache/xalan/serialize Encodings.java SerializerToHTML.java SerializerToText.java SerializerToXML.java
    Committer's log entry: Progress on Bugzilla Bug 1639 : Xalan escaping characters for ISO encodings other than ISO-8859-1. The problem is that you can't tell from the Java Writers if they can encode a character, and you can't tell which character they are going to encode to. So... Do a one-time-only reflection to see if a sun.io.CharToByteConverter for the specific encoding is available. I'm hoping this will work for most or all platforms... but only some extensive testing will tell for sure. If the CharToByteConverter is not available, it falls back to the old behavior. If it is available, use the canConvert method to see if the UTF-16 character can be encoded. If it can be, just send it to the writer, otherwise escape it. This doesn't need to be done for < 128, so I'm suspecting the performance hit won't be too bad. The alternative is to create lookups for all the encodings that tell which blocks of characters can't be encoded. Too much work for me this weekend, though it remains a possibility. I want to try the use of CharToByteConverter.canConvert first. One problem I've encountered is that CharToByteConverter.canConvert returns true for (utf-16 code points) 127-159. And so they go unescaped. How bad of a problem is this? This seems like a bug in the Java CharToByteConverter for ISO-8859-7. It remains to be seen if this problem exists with other encodings, or if this is the best approach.

    Committer's log entry: Fix for problem reported by Mike Starr <mike.starr@air2web.com>, where the transformation hangs for "foo[2] | bang" patters, i.e. unions with positional predicates. The fix is to have the iterators#nextNode() set m_lastFetched to DTM.NULL when m_foundLast is found to be true on function entry (after the cache check). This allows getCurrentNode() to fullfill it's contract of returning null if the last fetch was null. The bug occured after an optimization for positional predicates to have them not continue searching once the positional node was found, by setting m_foundLast to true.

    Modified: java/src/org/apache/xpath/axes WalkerFactory.java java/src/org/apache/xpath/compiler Compiler.java java/src/org/apache/xpath/patterns ContextMatchStepPattern.java StepPattern.java
    Committer's log entry: These are changes submitted (offline) by Mukund Raghavachari/Watson/IBM@IBMUS. This fixes a bug with match="chapter//footnote[1]" patterns. The main change here is minor to remove the automatic attachment of parent::* to simple step patterns. He has re-implemented executePredicates to be more efficient. Given a pattern such as row[6], it does not iterate over the entire axis until it reaches the node to see if it is the sixth node. Rather, starting from the current node, it works backwards (preceding siblings) until it either runs out of nodes or finds more than six nodes that match the predicate [I can explain it better if desired]. This optimization improves performance slightly overall. It helps decoy and patterns most (by about 10%). The other optimization that I implemented was the following. For a pattern foo[][3][][4] ..., where more than one predicate is a number (position check), in checking the predicate [4], the fact that the current node has passed foo[][3] implies that it is the only node that is the third node among its siblings that passes foo[]. Therefore, any subsequent position checks can be true if and only if the position is [1]. This optimization is not used by the xsltmark benchmarks and so does not offer any performance benefits.

Add XObject#create(Object val, XPathContext xctxt), which is called from TransformerImpl#setParameter(s), and FuncExtFunction#execute (for the return values of the extension). XBoolean and XNumber now also have Boolean and Number constructors, in which case the original object will also be returned from the object() method. This should make the conversion from java object to XObject consistent between function returns and setParameter. These changes should also fix a bug where NodeLists weren't being converted.

  • Committed by jkesselm@apache.org on 08/03/2001
    Added: java/src/org/apache/xml/utils NamespaceSupport2.java
    Committer's log entry: Replacement for org.xml.sax.helpers.NamespaceSupport; extends that API so it can be easily swapped in. Current changes; Minor code reorg. I'm sorry, but I find classes easier to read if fields are defined before methods reference them rather than at end, especially when inner classes are present. Punt stack vector in favor of doubly-linked list. (It was already singly-linked in parallel with the vector!) The whole dirty-tables concept was broken, because Context's ctor always called copyTables and thus always marked tables dirty. It also wasted some time setting itself only to be reset by setParent. I've fixed both by parameterizing the ctor and making copyTables specific to prep-for-new-declaration. (Could be moved back into the declaration method, for that matter.) I'm dubious about the caches in processName. As far as I can tell, Xalan per se never actually uses that method... The use of Hashtables is questionable. Hashtable is known to be inefficient and oversynchronized in older JVMs, and the fact that this is a bidirectional mapping suggests that an approach similar to our own String Pool -- lighter-weight, more targeted, hashing without reduplicating the two column tables -- would be a win. Since these are typically short sets, even simple linear search is worth considering!

In TransformerImpl#applyTemplateToNode, create a NodeSetDTM and pass it to m_xcontext.pushContextNodeList(cnl);. In NodeSetDTM fix getCurrentNode so that it doesn't use m_next-1 (which simply appears to be completely wrong). Do the same for NodeSet... though I don't think this will be called anywhere in Xalan.

    Committer's log entry: In response to regression posted on xalan-dev by John Gentilin <johnglinux@eyecatching.com> on 08/03/2001 06:49 PM. When the XNodeSet taks a DTMIterator, it will call val.getDTMManager();, which will call LocPathIterator#getDTMManager, which will call m_execContext..getDTMManager(), which means that setRoot has to be called on the iterator before it is added to XNodeSet. Thus, call setRoot on the OneStepIterator in create(Object, XPathContext) before it is added to the XNodeSet. The regression was related to fix for http://nagoya.apache.org/bugzilla/show_bug.cgi?id=2925.

In the cloneIterator function of PrecedingIterator, the cloned array was being sized for _maxAncestors, which defaults to 8.

    Modified: java/src/org/apache/xml/utils NamespaceSupport2.java
    Committer's log entry: Playing a hunch, I moved the Context objects out of NamespaceSupport2. They're now a second class in the same file rather than being an inner class. That reduces the size of the Context2 object, and its initialization time, by removing the need for it to carry a reference to the NamespaceSupport2 object that created it. Performance seems significantly improved... even (surprisingly!) on the getDeclaredPrefixes operation. Memory usage also seems better, as expected. NamespaceSupport2 is still acounting for about 5% of the time spent in the ResultTreeHandler, according to my latest trace. Apparently we are calling getDeclaredPrefixes an obscenely large number of times, and the Vector.elements call is adding up. We may want to look at where this is being called from and whether we can reduce the number of invocations.

In two routines, getPrefix and endElement, the appropriate prefix or URI was being located in the Vector using an indexOf. However, in this case where the prefix and the URI were the same, the routine was looking for the URI but finding the prefix instead of the URI. It tried tried to back up one to get the prefix and underflowed the Vector size.

    Committer's log entry: 3 small fixes to the build process ( to make it work with jdk1.4 and crimson) - exclude IncrementalSAXSource_Xerces if xerces is not detected - comment-out the "main" in IncrementalSAXSource_Filter.java ( it is a test, but has deps on xerces ) - don't try to load the compiler in syntetic/JavaUtils. This is a mess, it was debated on tomcat-dev and ant-dev, as you may know some people decided to remove the internal compiler class ( sun.tools.javac.Main ), and that brakes jasper, ant and now xalan. It seems right now the only portable way to run the compiler is via command line call in a separate process ( jikes can easily make up for the overhead of creating a new process and doesn't leave garbage ). Question: is synthetic used ? Seems like a very usefull package, but if xalan is not using it it might be better to move it to xml-commons or jakarta-commons or some other place.

    Modified: java/src/org/apache/xml/dtm/ref/sax2dtm SAX2DTM.java
    Committer's log entry: Fix bug 2727 (http://nagoya.apache.org/bugzilla/show_bug.cgi?id=2727). Attributes which contain a namespace prefix are indicated by placing a negative number in the appropriate entry in the m_dataOrQName array. The absolute value of this number is an entry in m_data. However, in this example, there were no text nodes before the first namespaced attribute so the entry in m_data had an array index of 0. This resulted in an entry of zero, not a negative number, in m_dataOrQName. This situation got several routines which tested for < 0 confused. I looked at several ways of fixing this but decided to just always allocate m_data.elementAt(0) entry to a dummy entry. The other solutions involved runtime checking which could slow down this piece of code and I felt that wasting one entry was worth it to not slow down the run time.

    Modified: java/src/org/apache/xpath/axes WalkerFactory.java java/src/org/apache/xpath/compiler Compiler.java java/src/org/apache/xpath/patterns ContextMatchStepPattern.java StepPattern.java
    Committer's log entry: These are changes submitted (offline) by Mukund Raghavachari/Watson/IBM@IBMUS. This fixes a bug with match="chapter//footnote[1]" patterns. The main change here is minor to remove the automatic attachment of parent::* to simple step patterns. He has re-implemented executePredicates to be more efficient. Given a pattern such as row[6], it does not iterate over the entire axis until it reaches the node to see if it is the sixth node. Rather, starting from the current node, it works backwards (preceding siblings) until it either runs out of nodes or finds more than six nodes that match the predicate [I can explain it better if desired]. This optimization improves performance slightly overall. It helps decoy and patterns most (by about 10%). The other optimization that I implemented was the following. For a pattern foo[][3][][4] ..., where more than one predicate is a number (position check), in checking the predicate [4], the fact that the current node has passed foo[][3] implies that it is the only node that is the third node among its siblings that passes foo[]. Therefore, any subsequent position checks can be true if and only if the position is [1]. This optimization is not used by the xsltmark benchmarks and so does not offer any performance benefits.

    Committer's log entry: Application of patch submitted by Ovidiu Predescu <ovidiu@cup.hp.com> for file, line, column number information for XML source document. [A made one change: m_sourceSystemId, m_sourceLine, and m_sourceColumn are not created with the member variable initializer, since they are initialized in setProperty.] The following patch is a rework of a previous patch I've submitted on May 24 against the Stree model, current at that time. This time the patch is against the DTM model, and makes use of DTM features to optimize the lookup time and storage requirements. I hope this time the patch gets incorporated in the CVS repository, before any major rework happens again ;-). As with the previous patch, there is no overhead in space or time if source information is not needed. From a user perspective, this feature can be turned on by passing the -L flag to Xalan when invoking it from the command line. Programmatically you can also enable it by invoking the setProperty method on the TransformerImpl: TransformerImpl impl = ((TransformerImpl) transformer); impl.setProperty(org.apache.xalan.transformer.XalanProperties.SOURCE_LOCATION, Boolean.TRUE); A Transformer "property" is different from a "feature": while a feature is specific to all the transformer instances and usually refers to an implementation aspect, a property is a runtime capability that is set per Transformer instance. Currently the only property added by this patch is the source location in the XML source document. The patch adds two methods to the DTM interface: public void setProperty(String property, Object value); public SourceLocator getSourceLocatorFor(int node); The second method is used to obtain the source location given a node handle. There are two ways you can make use of the source location. The first one is from within a stylesheet, where you can have something like this: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:nodeinfo="xalan://org.apache.xalan.lib.NodeInfo" version="1.0"> <xsl:template match="*"> //node <xsl:value-of select="name()"/> //file <xsl:value-of select="nodeinfo:systemId()"/> //line <xsl:value-of select="nodeinfo:lineNumber()"/> //column <xsl:value-of select="nodeinfo:columnNumber()"/> <xsl:apply-templates/> </xsl:template> </xsl:stylesheet> If no arguments are passed to the systemId(), lineNumber() or columnNumber() functions, the corresponding information of the current context node is returned. A node can be passed as argument to the above functions, in which case the corresponding information about that node is returned. If a node set containing multiple nodes is passed as argument, only the information of the first node in the set is returned. The second way of obtaining the source location is programmatically. Given a Node instance, one can obtain the owner DTM and the node handle (an integer) that represents the node. Unfortunately I didn't see any way of hiding this: if you find one please let me know and I'll fix it. The following example is extracted from PrintTraceListener and illustrates the API: Node sourceNode = ev.m_sourceNode; int nodeHandler = ((DTMNodeProxy)sourceNode).getDTMNodeNumber(); SourceLocator locator = ((DTMNodeProxy)sourceNode).getDTM() .getSourceLocatorFor(nodeHandler); m_pw.println("Selected source node '" + sourceNode.getNodeName() + "', at " + locator);

    Modified: java/src/org/apache/xalan/serialize SerializerToHTML.java
    Committer's log entry: Application of patch submitted by Benjamin Riefenstahl <Benjamin.Riefenstahl@ision.net> Motivation: We are using Xalan to generate HTML pages. We have the requirement to integrate code for ad banners. The ad server provider has written the code to use with compatibility to NetScape 4 in mind. The code uses the NetScape proprietory <LAYER> element and <IFRAME> elements for other browsers. The SRC attributes of these elements contain URLs with several URL parameters separated by '&', as is the common convention. Problem: The code is integrated in our XSL stylesheets. In the stylesheet the '&' has to be written as the entity '&amp;'. That's ok. The problem is that in the output the '&' is also written as '&amp;' which is not ok, because NetScape doesn't understand that. OTOH the same URL is written with '&' when used in an <A> element. Solution: This goes down to a different handling of attribute values in the class SerializeToHTML, depending on whether the attribute in question is known to contain a URI or not. Xalan knows this for <A> but not for <LAYER> and <IFRAME>. When I compare the list in SerializeToHTML.java with the HTML specs, I find a couple of other missing URI attributes in SerializeToHTML.java. When I add the missing pieces, the generation works fine. Patch: Here is the patch (diff -c) for xalan-j_2_2_D6. I also have one for xalan-j_2_0_1 which is the version I actually tested this with. Please let me know if this is insufficient or the patch is wrong or if there is something else I can do to fix this problem.

    Committer's log entry: Starting to phase out Coroutine*Parser* in favor of IncrementalSAXSource*. The latter simplifies the code, and should help us avoid some of the confusion that can arise in using the older tools. Most importantly, it greatly simplifies the calling sequences, by discarding the "which file do you want to parse" and "do you want to parse any more files" transactions. These now operate _only_ as filters, and only as single -use (though in fact the Xerces-specific version is reusable, and we may reintroduce that feature in the generic filtering version at a later date). Note too that we have swept the CoroutineManager completely under the covers of the filter's API. There's no particular reason to expose that implementation detal to the outside world. Still to be done: Rework the rest of Xalan to use the new code.

Changes for Xalan-Java 2.2.D6
 

Important: Xerces has added a number of DOM level-3 methods to its DOM interfaces. The DOM level-3 proposal is currently a working draft (it is not yet a W3C recommendation), and Xalan does not support these new methods. To run Xalan in the JDK 1.1.8 platform, you must put xalan.jar (with its DOM level-2 interfaces) in front of xerces.jar on the system class path. If you want to rebuild Xalan (on JDK 1.1.8 or higher), you must put Xalan in front of xerces.jar the system class path.

This beta release includes the following non-XSLTC code changes:

  • Costin Manolache has slightly modified the CoRoutine stuff so that a you can compile and run everything but the CoRoutineXercesParser without having Xerces on the classpath.

  • Joseph Kesselman added chunked int array stuff to address our scaling problems that Mukund & co. uncovered. This was a fairly mechanical, but still substantial, change. No bugs have yet been discovered that relate to this. This is probably the most controversial change.

  • The Process class now outputs incrementally if the output is standard out. This is mostly for testing purposes, but it makes general sense.

  • Bug was fixed with setting the incremental flag in TransformerFactoryImpl. Clearly the change was made but never tested. Simply a missing 'else'.

  • Fix for Bugzilla Bug 2275, Xalan did not fire the right templates. This was substantial and somewhat risky. Xalan had several problems related to the last() function. Fixes cover four axes files.

  • Change PrintTraceListener to output the file, as well as the line numbers. This is really a feature change, but simple, and aids diagnosing problems with multi-part stylesheets.

  • XPath fix: the XPath API wasn't working correctly due to a problem with with NodeSet/NodeIterator adapters. This fix ended up interacting quite a bit with the #2275 fix.

  • Fix for the Norm Walsh bug posted 06/20/2001: iterators weren't always being cloned correctly from the variable value stack. This fix is not without some risk, though we haven't seen any problems since Scott Boag made it.

  • David Bertoni added missing html element properties to SerializerToHTML.java.

  • Shance Curcuru modified TransformerFactoryImpl.setAttribute() to accept a String ("true" or "false") as well as a Boolean object to set the value of a Boolean attribute.

  • TransformerHandlerImpl was threading when incrementality is turned off. Scott Boag has fixed this bug.

Changes for Xalan-Java 2.2.D2
 

This release includes the following changes:

The primary focus of the 2.2 Developer releases is incorporation of all our work over the past several months on the Document Table Model (DTM).

As a result of the changes in *internal* api, you may encounter problems with extensions. We have done some bug fixing in support for extensions since 2.2.D1. John Gentilin is working on fixing the SQL library extension,which currently is broken. Please report any problems you find (see bugs).

The DTM and related work provides faster performance and less accumulation of garbage... though it is an ongoing battle. Brief summary:

  • The DTM identifies nodes with 32-bit integer handles. The DTM has many features, including direct character dispatch to SAX2, native DTM iterators and "traversers", multiple document management, etc.

  • Joe Kesselman's CoRoutine parsers, which are in a threaded SAX flavor and in a Xerces parseMore() flavor (no threads). These do away with the "race" conditions that occured in the original code, and should make Xalan much more robust.

  • *Much* more robust XPath itteration. The "waiting" iterators of old are no more, and good riddance. There is stil lots more we want to do with this mechanism. (There is something here called MatchIterators, but it's not being used yet for various reasons. We will be taking advantage of these down the line.)

  • A fair amount of XObject creation reduction. You can now get boolean, number, nodeset, and string values directly from an Expression, instead of going through an XObject.

  • XMLString, which allows us to work with string objects that don't wrap Java's String object. These objects get their character data from an array or Fast String Buffer.

  • Serializers now only do internal buffering if they know they are writing to a FileStream.

  • The variable stack mechanism has been redisigned, so that it is no longer so interpretive, and we believe it is much more robust.

  • Some small amount of stylesheet rewriting (but not yet redundent expression elimination), in particular to reduce full RTF creation and interpretation.

Xalan-Java implements two DTM performance features that you can control with the TransformerFactory setAttribute() method. See DTM performance settings


Changes for Xalan-Java 2.1.0
 

This release includes a number of bug fixes to Xalan-Java and TrAX. We have also enhanced the ApplyXSLT servlet. It can now be set up to use a compiled Templates object to respond to multiple client transformation requests involving the same stylesheet.

    Modified: java/src/org/apache/xalan/processor StylesheetHandler.java java/src/org/apache/xpath Expression.java XPath.java XPathContext.java java/src/org/apache/xpath/compiler Compiler.java XPathParser.java

    Modified: java/src/org/apache/xml/utils FastStringBuffer.java
    Committer's log entry: Reworked "chunk growth" algorithm again. Growing mode not yet adequately tested, but fixed-size mode (which is what Xalan is currently using) is simpler code and shows improved performance.

  • Committed by jkesselm@apache.org on 03/22/2001
    Modified: java/src/org/apache/xml/utils FastStringBuffer.java
    Committer's log entry: We've reworked the algorithm again. The fixed-chunk-size mode (initial and max. chunk sizes equal) runs essentially unchanged, though with a few cycles less overhead. The variable-chunk-size mode now uses a recursive-encapsulation scheme, where the first chunk may itself be a FastStringBuffer whose total length equals one chunk; every so often we push the existing data down one level and restart with a larger chunk size. The new scheme has been stress-tested and is apparently working. At this writing, however, Xalan uses only the fixed-size mode (initial size equals max size), and no effort has been made to find the optimial values for the tuning parameters. It does appear likely that the best values will vary with usage patterns, but we hope to find a good compromise. I'll probably be putting this aside for a while to work on other things. If someone wants to experiment with varying the block sizes and how frequently they grow, and suggest good performance/memory tradeoff points, go for it!

    Modified: java/src/org/apache/xalan/templates OutputProperties.java
    Committer's log entry: Patches submitted by Patrick Moore <patrickm@rioport.com> on 03/15/2001 01:25 PM: This proposed change does a number of things: 1. Problem: HTML output method does not uses XML output properties as default. In both org/apache/xalan/templates/output_html.properties and in the java doc for org/apache/xalan/templates/OutputProperties#getDefaultMethodProperties(Strin g) It specifically states that all OutputProperties use the output_xml.properties as a base. In the code this is not true for html. This is now changed to match the comments 2. Problem: unclear IOException. If there was a problem loading the XML properties file. The wrapped exception now will say which file was trying to be loaded. If the file did not exist I was getting a very strange "Stream closed" IOException message. 3. Problem: the streams were not closed after reading the property file. Fixed. 4. Problem: the double-check locking mechanism does not work in Java (see bug #919) <http://www.javaworld.com/javaworld/jw-02-2001/jw-0209-toolbox.html> 5. QUESTION: now if there is a default properties (i.e. output_xml.properties has been loaded) but the expected properties file does not exist a error message will be printed to System.err and the processing will continuing using just the default properties (output_xml.properties) I felt that this is the best behavior. (comment by sboag: I think it's better to throw a runtime exception in this case. but we can discuss this over time. For now the patch was modified to do the runtime exception).

    Committer's log entry: This check-in contains a couple things that overlapped on my system, so I'm checking them in together. 1) Unfinished (in progress) implementation of TransformSnapshot mechanism, which will hopefully allow a result ContentHandler to take a snapshot at a given point, and the restart execution from that point at some later time. For tooling support. 2) Check to make sure SourceTreeHandler isn't being entered twice, which is related to the cocoon bug from a couple of weeks ago. This will just help diagnose such a problem in the future. 3) Removed the error stack trace print from postExceptionFromThread. 4) Report exception in SourceTreeHandler#endDocument after the join, if we can determine that the posted exception won't be caught elsewhere. 5) removed some catches that simply rethrew the exception (thanks to Patrick Moore <patrickm@rioport.com>). See my note on 3/27/2001 to Patrick for more info on the last two.

The default implementation is identical with what we had, using new Thread() and start() - waitTread() - waits for a task to end. The default impl. is identical with the previous code, using thread.join(). Someone wanting to use a thread pool for xalan will have to extend the ThreadControler and override the 2 methods, then call setThreadController. Xalan itself doesn't implement a thread pool right now ( for mosts uses it's not even needed - if you just do few transforms for example ), instead a server that runs xalan could plug it's own thread pool.

Changes for Xalan-Java 2.0.1
 

This release includes a number of bug fixes to the Xalan-Java and TrAX core and Xalan-Java 1 compability API. We have also

  • Entered all known Xalan-Java 2 bugs in the Apache Bugzilla database

  • Added support for using custom URIResolver, EntityResolver, and ContentHandler implementations with the command-line utility

  • Upgraded from Ant 1.2 to Ant 1.3 for our builds (the new ant.jar is in the bin directory).

"//table[1]" is equivelent to "/descendant-or-self::node()/table[1]", and so must return the first table child of each table-inst element. An optimization was optimizing this to "/descendant-or-self::table, which is fine as long as indexing isn't used. Since we can not tell until runtime if indexing is being used, we have to turn of this optimization for all predicated "//foo[xx]" patterns.

    Modified: java/src/org/apache/xalan/transformer TransformerImpl.java
    Committer's log entry: Fix for bug originally reported by Daryl Beattie <DarylB@screamingmedia.com> on 02/14/2001 04:16 PM. A hang was occuring inside the use of a Result Tree Fragment. When the result tree fragement was being created, the Redirect extension was being called, which called createResultContentHandler which set the ContentHandler in the Transformer, but not in the ResultTreeHandler. Then, Redirect called Transformer#executeChildTemplates( ElemTemplateElement elem, Node sourceNode, QName mode, ContentHandler handler) which saves the reference to the original content handler in the transformer, and then sets the new one by calling setContentHandler, which sets the ContentHandler in the ResultTreeHandler as well as the Transformer. When it tried to restore the old ContentHandler, it restored the value in the ResultTreeHandler to a Serializer, instead of the correct ContentHandler. When transformToRTF then called endDocument on it's resultTreeFragment, the event was sent to the Serializer instead of the SourceTreeHandler, and thus the isComplete flag was not set, and thus the hang. (whew!) The fix is in executeChildTemplates save the value of the resultTreeHandler's contentHandler as well as Transformer's content handler, and restore them both. A more architectual fix could be made, but not without high risk, so I think this is the best and safest way to fix it.

    Committer's log entry: Fix for http://nagoya.apache.org/bugzilla/show_bug.cgi?id=741. 1) ResultTreeHandler now implements the TransformState interface. 2) Queued state such as the current node and the current template is stored as part of QueuedStartElement. Storage will only occur if the ContentHandler implements TransformClient. 3) When state is requested (for instance TransformState#getCurrentElement()), if the queued element is null or not pending (for instance, in a characters event), it will get the state from the transformer, otherwise it will get the state from the queued element. Other fixes were attempted for this problem, including trying to get rid of queueing altogether, and flushing a bit earlier before the state was pushed on the various stacks, but both of these had show-stopping issues (see discussions on xalan-dev). Note that for the moment the ContextNodeList is node cloned as it needs to be in order for TransformState#getContextNodeList.

    Modified: java/src/org/apache/xalan/templates ElemParam.java java/src/org/apache/xpath Arg.java VariableStack.java
    Committer's log entry: The field Arg.isParamVar was attempting to serve two functions: to indicate variable Frame entries which are not currently activated and to indicate Frames containing parameters passed with xsl:with-param. When processing was finished for a node in a node-set, the isParamVar flag was turned on to indicate the Frame slot was available. Unfortunately, this also indicated that the item was passed as a parameter which it wasn't. This fix changes isParamVar into to fields, isAvailable which indicates that the slot is available and isFromWithParam indicating the Frame slot came from an xsl:with-param or a top-level parameter passed in via the tranformerImpl.setParameter() API. I have tested this change against the conformance suite and had no regression. I've also submitted a test case which fails on the existing codebase but works okay after this fix. It is possible that I've missed something with regard to the API setParameter calls but we can fix those if problems are reported.

    Committer's log entry: The DOM2Helper#isNodeAfter(Node node1, Node node2) method has been fixed so that it no longer does the try/catch thing if one of the nodes doesn't implement DOMOrder, but instead does an instanceof test. In StreeDOMHelper, it overloads this method and *does* do the try/catch business, since almost always both nodes will implement DOMOrder in this case, and this will be faster than an instanceof test. Also, in various classes, I did some stuff to try and make sure that a DOM2Helper wasn't being created and used when a StreeDOMHelper is needed. This addresses http://nagoya.apache.org/bugzilla/show_bug.cgi?id=800 and should give a good performance fix for foreign DOM processing.

Even if the Xerces people change this >>behavior, is this correct? > > Yes. If your description of the problem is accurate (you should probably > submit a more detailed case so it can be reproduced in the lab), this is a > parser/DOM-builder bug.

    Modified: java/src/org/apache/xalan/lib/sql ExtensionError.java
    Committer's log entry: Removed ( commented out ) dump() method and the imports in ExtensionError. So far the method doesn't seem to be used ( no warning in the compile ). The problem is that this method is breaking the build with crimson ( since it uses xerces-specific classes ). It is possible to implement it on top of the serialization classes that are part of xalan - if someone needs the method I'll try to port it.

Changes for Xalan-Java version 2.0.0
 

Release 2.0 includes several bug fixes to the Xalan-Java and TrAX core and to the Xalan-Java 1 compatibility API. We also updated bsf.jar to the Bean Scripting Framework (BSF) release candidate 2.2, which fixes a bug running JPython extensions.

Core bug fixes:

  • A threading problem showed up when using multiple processors. We fixed it by using a separate XPathContext object to do whitespace node matches (xsl:strip-space).

  • Fixed a bug running Norm Walsh's DocBook stylesheets by not setting the variable stack position if the FilterExprWalker is not owned by a top-level NodeIterator.

  • Fixed a problem with null namespace being passed from xsl:element. This bug also surfaced while processing DocBook stylesheets.

  • In the interest of stability, we now treat "unknown error in XPath" as a fatal error.

  • Added support in stylesheet processing instructions for "text/xml" and "application/xml+xslt" mime types.

  • Fixed tokenizing of stylesheet processing instructions to allow parameters to be passed to server in href attributes.

  • Fixed a bug passing Transformer creation error messages to ErrorListener when an ErrorListener has been set on TransformerFactory.

  • When using an Exception to instantiate a FactoryConfigurationError (extends Error), we now propagate the Exception message to super().

  • Added defensive code to ElemTemplateElement for handling a null URI.

  • When using an Exception to instantiate a TransformerException (extends Exception), we now propagate the Exception message to super() rather than a generic message.

  • Fixed a bug (the generation of an unwanted entity reference) performing the identity transformation (see Serializing output) with an XML document containing a DOCTYPE declaration.

  • Message manager modified so that the SourceLocator must always be passed in, which will make a major difference in getting line number information.

  • xsl:element's handling of namespace attribute and prefix in name attribute changed so that it no longer manufactures prefixes... it always tries its best to match the prefix entered.

  • Bug fixed with namespace contexts in the stylesheet processor. The bug could cause <a xmlns:a="x"><b> to produce <a xmlns:a="x"><b xmlns:a="x">.

  • Modified processing of xsl:message to enhance it as a debugging aid. Line numbers are now output with each message. If the terminate attribute is true (the default is false) the message is sent to the console, and an exception is thrown with the message "Stylesheet directed termination".

  • In TransformerException, check that the cause != null when checking for a contained exception.

  • Fixed a problem validating non-namespaced attributes and a problem allowing non-namespaced attributes to be children of the stylesheet element.

  • Fixed checking of number of arguments in document() function.

  • Fixed problem with mutation of templates at run time. Templates resolution now takes place during the compose() method.

  • Fixed some minor threading issues in org.apache.xalan.stree (Child, Parent, ElementImpl, SourceTreeHandler).

  • Synchronized TrAX API functions subject to mutation to prevent mutation during a transformation.

  • Fixed bug reported by Jano Elovirta: substring() was returning an error if the start index is larger than the string.

  • Set StringKey.toString() to return the underlying String (m_str), thus avoiding a potential symmetry problem with the equals() method reported by Ito Kazumitsu.

  • In response to note from Ito Kazumitsu, changed Java encoding name "EUCJIS" in FormatterToXML to "EUC_JP".

  • When Xalan creates a FileOutputStream, it now closes the stream before exiting.

  • Fixed handling of an exception that can be thrown while building a DOM.

  • Fixed a problem reported by Dimitry Voytenko serializing compiled stylesheets.

  • For support of applets, modified TransformerFactory System.getProperty() calls to catch SecurityExceptions.

  • Fixed a bug reported by Krishna Mohan Meduri setting output properties.

  • Fixed error recovery when xsl:element encounters a bad name or unresolvable prefix.

  • Added AbstractMethodError handling to existing NoSuchMethodError handling as a fallback to the XMLReaderFactory for XML parsers that do not implement the JAXP parsers interface for creating an XMLReader

  • Fixed bug with cloned iterators reported by Tim Sean.

  • Fixed null pointer exception that could occur with getValue("xxx").

  • Fixed bug reported by Tim Sean handling the xml:space attribute.

Bug fixes in the Xalan-Java 1 compatibility API:

  • Fixed ProblemListener (for processing error messages) to derive from Xalan-Java 2 ErrorHandler.

  • Fixed evaluation of stylesheet string parameters to conform to Xalan-Java 1 behavior (expressions for Xalan-Java 1 vs. String objects for Xalan-Java 2).

  • Added XPathSupport and XPathSupportDefault, and fixed the derivation of XObject sub-types (XString, etc.).

  • Fixed bug with XSLTProcessor process(xmlIn, null, out) method so that it uses the StylesheetRoot (if one exists) that has been created with the processStylesheet() method.

Changes for Xalan-Java version 2.0.D07
 

Xalan-Java 2.0.D07 incorporates a Xalan-Java 1 compatibility jar, some performance enhancements, and a number of bug fixes for bugs found in version 2.0.D06.

  • Fixed handling of disable-output-escaping="no". Previously, once it was turned on, it could not be turned off.

  • Fixed a bug with whitespace handling where Xalan was incorrectly checking for whitespace stripping before collation of multiple whitespace events into a single text node.

  • Whitespace stripping wasn't working with input DOMs before. This is now fixed.

  • Fixed many exception handling problems and problems with error reporting.

  • Fixed a bug resetting parameters in Transformer clearParameters().

  • Fixed a bug where CDATA sections were not matching the text() node test.

  • Made better memory allocation problem with result tree fragments.

  • Made result tree fragment parsing of numbers consistent with strings.

  • Exceptions thrown from extensions should now be properly reported via the error listener.

  • Fixed hard-coded stack dump set off by m_reportInPostExceptionFromThread variable.

  • Fixed intermittent threading problem with text nodes being dropped.

  • Fixed problem with variable evaluation inside of union expressions.

Changes for Xalan-Java version 2.0.D06
 

We have fixed the bugs reported in Xalan-Java 2.0.D05. Along with several other enhancements, we have also fixed a number of bugs found by testing and our users:

  • Fixed some threading problems and improved support for handling Exceptions thrown in a secondary thread.

    Note: To support incremental output, Xalan-Java performs the transformation in a second thread while building the source tree in the main thread.

  • Fixed problems encountered in piping (utilizing transformation output as input for another transformation).

  • Fixed problems handling attributes and adding attributes to result tree.

  • Added defensive checking for null entities, null namespaces, and empty strings passed in for URIs and local names.

  • We now conform to the SAX convention of representing null namespaces with empty strings.

  • Fixed a bug encountered evaluating a variable in a predicate expression applied to child nodes.

  • Changed names of serializers from FormatterToXxx to SerializerToXxx. See Package org.apache.xalan.serialize.

  • Improved debugging support in a number of areas.

Changes for Xalan-Java version 2.0.D05
 

All of the bugs reported in Xalan-Java 2.0.D01 have been fixed. The remainder of this section discusses two changes that we believe are of particular importance:

TrAX

The Transformation API for XML (TrAX) that Xalan-Java 2 implements has undergone substantial revisions since the release of Xalan-Java 2.0.D01. TrAX has joined the Java API for XML Parsing (JAXP) as part of the Sun® Java Specification Request 63. Accordingly, the TrAX package names have changed. The conceptual organization has also changed somewhat: The primary transformation interfaces are defined in javax.xml.transform, with concrete classes for managing stream input/output, SAX parsers and ContentHandler, and DOM parsers and DOM trees in javax.xml.transform.stream, javax.xml.transform.sax, and javax.xml.transform.dom. For more information, see TRaX (Transformation API for XML), and review Usage Patterns.

Output properties

The handling of xsl:output properties has changed: org.apache.xalan.serialize.OutputFormat and apache.xalan.templates.OutputFormatExtended were removed and replaced with org.apache.xalan.templates.OutputProperties. The SerializerFactory getSerializer() method now takes Properties rather than a String indicating the output method. You can replace getSerializer("xml"), for example, with getSerializer(OutputProperties.getDefaultMethodProperties("xml")).

HTML, XML, and text xsl:output properties are specified in property files in org.apache.xalan.templates: output_html.properties, output_xml.properties, and output_text.properties.

You can start using the output properties defined in these files in your stylesheets. For example, you can turn URL escaping off in HTML output with
{http\u003a//xml.apache.org/xslt}use-url-escaping=no
and you can control indenting with
{http\u003a//xml.apache.org/xslt}indent-amount=n

NoteThe colon after the "http" protocol must be escaped.

Character-to-entity mapping is specified in org.apache.xalan.serialize: HTMLEntities.res and XMLEntities.res. You can override entity ref mapping from a stylesheet. For example:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
         xmlns:xalan="http://xml.apache.org/xslt" version="1.0">

  <xsl:output xalan:entities="myentities.ent"/>

  <xsl:template match="/">
    <out>&#125;</out>
  </xsl:template>

</xsl:stylesheet>

=== myentities.ent ===

quot 34
amp 38
lt 60
gt 62
lala 125

The output is:

<?xml version="1.0" encoding="UTF-8"?>
<out>&lala;</out>
