The Microsoft MSXML 2.0 parser forces datatype validation even when data is not being validated. For example, in an XSL stylesheet that outputs a datatyped node, if the value of the node is specified using the <xsl:value-of> tag, and the datatype of the node is number, then the parser generates an error.

The MSXML parser, version 2.5 (5.0.2920.0), corrects this problem.

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

This problem has been fixed in Version 2.5 of the MSXML parser. To download the latest version of the parser, visit http://msdn.microsoft.com/xml/default.asp. (http://msdn.microsoft.com/xml/default.asp)

Steps to Reproduce Behavior

To reproduce this problem, do the following:

1. Insert the following code into a new text file, and save the file as test.xml:

   <?xml-stylesheet type="text/xsl" href="test.xsl" ?>
   <items>
      <item value="1000"/>
   </items>
   					

2. Next, insert the following code into another new text file, and save the file in the same location as the previous file, as test.xsl:

   <?xml version="1.0"?>
   <xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">
      <xsl:template match="http://support.microsoft.com">
         <output xmlns:dt="urn:schemas-microsoft-com:datatypes">
            <xsl:for-each select="items/item">
               <value dt:dt="number"><xsl:value-of select="@value"/></value>
            </xsl:for-each>
         </output>
      </xsl:template>
   </xsl:stylesheet>
   					

3. Browse to the test.xml file using a Microsoft Internet Explorer Web browser on a computer with version 2.0 of the MSXML parser installed. Note that a parse error is generated because the datatype of the value tag is specified to be a number, and the contents of the node is another tag. The value-of tag should generate a numeric value in the output; instead, the parser generates an error.
