View products that this article applies to.

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.

Steps to Reproduce Behavior

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>

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>

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.
