FIX: XQL Operator "//" Matching in MSXML 3.0 Is Not Backward Compatible (291595)



The information in this article applies to:

  • Microsoft XML 3.0

This article was previously published under Q291595

SYMPTOMS

The "http://www.w3.org/TR/WD-xsl" namespace in MSXML versions earlier than 3.0 allows the XQL recursive descent (//) operator to be followed by nothing. The "http://www.w3.org/1999/XSL/Transform" namespace in MSXML version 3.0 does not allow the // operator to be followed by nothing.

RESOLUTION

The problem is discussed here for reference purposes only.

Use the current namespace and its corresponding methods instead of the previous namespaces and methods.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This bug was corrected in Microsoft XML 3.0 Service Pack 1.

Steps to Reproduce Behavior

  1. Paste the following code into a new text document, and save the file as Repro.xml:
    <?xml version='1.0' encoding='ISO-8859-1'?>
    <?xml-stylesheet type="text/xsl" href="repro.xsl"?>
    <ROOT>
     <MESSAGE>
      <font color="red">red text</font>
     </MESSAGE>
    </ROOT> 
    					
  2. Paste the following text into another new document, and save the file as Repro.xsl in the same location as the XML file you just created:
    <?xml version='1.0' encoding='ISO-8859-1'?>
    <xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">
      <xsl:template match="/">
        <xsl:apply-templates select="ROOT" />
      </xsl:template>
      <xsl:template match="ROOT">
        <xsl:for-each select="MESSAGE">
          <xsl:apply-templates select="." />
        </xsl:for-each>
      </xsl:template>
      <xsl:template match="MESSAGE//"><xsl:copy><xsl:apply-templates select="@*"/><xsl:apply-templates /></xsl:copy></xsl:template>
    </xsl:stylesheet>
    					
  3. In Microsoft Internet Explorer, browse to Repro.xml. In MSXML 2.5, the output data shows the following:
    <MESSAGE><font color="red">red text</font></MESSAGE> 
    					
    In MSXML 3.0, the output data shows the following:
    <MESSAGE><font>red text</font></MESSAGE>
    					
    Note that the color="red" attribute section is missing in the MSXML 3.0 output data. The output text "red text" appears in red colour in MSXML 2.5 and in black MSXML 3.0.
