Mukul,

I have to agree.  I normally figure this stuff out pretty quickly, but
this one has me completely stumped.  

Hopefully someone will chime in on this.

Subject: [xsl] Re: 

After trying to solve the problem, I feel, this
problem is difficult to solve.. Here is the XSLT I
tried ;)

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt">
<xsl:output method="html" version="1.0"
encoding="UTF-8" indent="yes"/>
	
<xsl:key name="x" match="/School/Grade" use="Name"/>
<xsl:key name="y" match="" use="" /> <!-- ?? -->
	
<xsl:template match="/School">
  <xsl:variable name="gradeRTF">
    <xsl:for-each select="Grade">
	<xsl:if test="generate-id(.) = generate-id(key('x',
Name)[1])">
	   Grade: <xsl:value-of select="Name"/>
	</xsl:if>
    </xsl:for-each>
  </xsl:variable>
		
  <xsl:value-of select="msxsl:node-set($gradeRTF)/."
/>
  <!-- process the node-set; Apply Muenchian grouping
to the node-set -->

</xsl:template>

</xsl:stylesheet>

There should be a key defined, from the node-set
msxsl:node-set($gradeRTF). Lets assume, the key name
is 'y' .. But we cannot define xsl:key below
<xsl:value-of select="msxsl:node-set($gradeRTF)/." />
, which IMO is required, to solve the problem ;)

Can somebody, please shed some light, on the problem
;)

Regards,
Mukul
