Re: Grouping elements

Following is a Muenchian grouping solution..

<?xml version="1.0"?> 
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">
 
 <xsl:output method="text" /> 
 
 <xsl:key name="by-model" match="car" use="model" />
 
 <xsl:template match="/cars">
    <xsl:for-each select="car[generate-id() =
generate-id(key('by-model',model)[1])][count(key('by-model',model))
&gt; 1]">
      <xsl:sort select="model" order="descending" />
      Car: <xsl:value-of select="model" /><xsl:text>  
</xsl:text><xsl:value-of select="name" /><xsl:text>
</xsl:text><xsl:value-of select="categ"
/><xsl:text>&#xa;</xsl:text>
      occurence: <xsl:value-of
select="count(key('by-model',model))"
/><xsl:text>&#xa;</xsl:text>
      Total stock: <xsl:value-of
select="sum(key('by-model',model)/stock)"
/><xsl:text>&#xa;</xsl:text>
    </xsl:for-each>
 </xsl:template>
 
</xsl:stylesheet>
