Re: [xsl] Can I change variable contents.

[Mukul Gandhi <mukulgandhi2003@xxxxxxxxxxx>]

Hi Vikram,
  Please try the XSL -

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text" version="1.0"
encoding="UTF-8" indent="yes"/>
	
<xsl:key name="x" match="/root/Tag"
use="substring-before(@value, ':')" />
	
<xsl:template match="/root">
   <xsl:for-each select="Tag">
       <xsl:if test="generate-id(.) =
generate-id(key('x', substring-before(@value,
':'))[1])">
            <xsl:for-each select="key('x',
substring-before(@value, ':'))">
              <xsl:value-of
select="substring-after(@value, ':')" /><xsl:text>
</xsl:text>
            </xsl:for-each> from <xsl:value-of
select="substring-before(./@value, ':')" />
       </xsl:if>
   </xsl:for-each>
</xsl:template>
	
</xsl:stylesheet>

It uses Muenchian method for grouping as suggested by
David Carlisle.

Mukul
