If I was to group all the subitems, I'd use something like <xsl:key
name="subs" match="BODY/ITEM" use="SUBITEM" />.
Can I apply the same sort of logic within an item group, to get some output something like :
Item AA
Subitems 1, 2, 3
Item BB
Subitems 1,4
Item CC
Subitems 2, 3

Hi,

The trick is to extend the 'key' elment's 'use' attribute with more information, using the 'concat()' function. e.g.:

<xsl:stylesheet xmlns:xsl = "http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method = "text"/>

<xsl:key name="subs" match="SUBITEM" use="concat(../ID,.)" />

<xsl:template match="ITEM"> Item <xsl:value-of select="ID"/> Subitems <xsl:apply-templates select="SUBITEM[generate-id()=generate-id(key('subs', concat(../ID,.)))]"/> </xsl:template>

<xsl:template match="SUBITEM">
<xsl:value-of select="."/>
<xsl:if test="position()!=last()">, </xsl:if>
</xsl:template>

</xsl:stylesheet>
