FIX: A System.Xml.Xsl.XsltException exception occurs when you try to perform an XSLT transformation by using an XSLT style sheet that uses the format-number function (832757)

MORE INFORMATION

Steps to reproduce the behavior

1. Create a Console Application project

   1. Start Microsoft Visual Studio .NET 2003.
   2. On the File menu, point to New, and then click Project.
   3. Under Project Types, click Visual C# Projects, and then click Console Application under Templates.
   4. In the Name box, type FormatNumConsole.
   5. Click OK. By default, the Class1.cs Code window opens.

2. Create an XSLT style sheet that uses the format-number function

   1. In Solution Explorer, right-click FormatNumConsole, point to Add, and then click Add New Item. The Add New Item - FormatNumConsole dialog box appears.
   2. Under Categories, click Local Project Items.
   3. Under Templates, click XSLT File.
   4. In the Name box, type format-number.xslt, and then click Open. The format-number.xslt Code window opens.
   5. Replace the existing XML code with the following XML code to create a template for the presentation of XML data:

      <?xml version="1.0" encoding="UTF-8"?>
      <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
          <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
          <xsl:template match="/">
              <table>
                  <xsl:apply-templates />
              </table>
          </xsl:template>
          <xsl:template match="number">
              <tr><td><xsl:value-of select="format-number(.,'#,##0;(#,##0)')"/></td></tr>
          </xsl:template>
      </xsl:stylesheet>

3. Create an XML file that provides XML data

   1. In Solution Explorer, right-click FormatNumConsole, point to Add, and then click Add New Item. The Add New Item - FormatNumConsole dialog box appears.
   2. Under Templates, click XML File.
   3. In the Name box, type format-number.xml, and then click Open. The format-number.xml Code window opens.
   4. Replace the existing XML code with the following XML code to provide XML data:

      <?xml version="1.0" encoding="UTF-8"?>
      <root>
          <number>1000</number>
      </root>

4. Try to perform an XSLT transformation by using the XSLT style sheet and the XML file

   1. Switch to the Class1.cs Code window.
   2. Replace the existing code with the following code to use the XslTransform class to transform the XML data by using the XSLT style sheet.
      
      Note In the following code, use the appropriate file paths in the calls to the XPathDocument constructor and the xsltProcessor.Load method:

      using System;
      using System.Xml;
      using System.Xml.XPath;
      using System.Xml.Xsl;
      using System.IO;
      using System.Text;
      
      namespace FormatNumConsole
      {
          class Class1
          {
              [STAThread]
              static void Main(string[] args)
              {
                  try
                  {
                      StringBuilder sb = new StringBuilder();
                      StringWriter sw = new StringWriter(sb);
      
                      // Load the XML data that you want to transform.
                      XPathDocument xmlDoc = new XPathDocument("C:\\FormatNumConsole\\format-number.xml");
      
                      // Load the XSLT style sheet that uses the format-number function.
                      XslTransform xsltProcessor = new XslTransform();
                      xsltProcessor.Load("C:\\FormatNumConsole\\format-number.xslt");
      
                      // Transform the XML data, and then send the output to the console.
                      xsltProcessor.Transform(xmlDoc,null,sw,null);
                  }
                  catch(Exception ex)
                  {
                      // Display the inner exception and the exception message.
                      Console.WriteLine(ex.InnerException.ToString());
                      Console.WriteLine();
                      Console.WriteLine(ex.Message);
                      Console.ReadLine();
                  }
              }
          }
      }

   3. Build the application, and then run the application. The output that is mentioned in the "Symptoms" section appears in a console window.
