Hi Daren, This is a short solution: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text"/> <xsl:key name="kIndex" match="@index" use="."/> <xsl:template match="/"> <xsl:variable name="x"> <xsl:for-each select="/*/*/*/*/@index [generate-id() = generate-id(key('kIndex', .)[1])]"> <xsl:value-of select="'Z'"/> </xsl:for-each> </xsl:variable> <xsl:value-of select="string-length($x)"/> </xsl:template> </xsl:stylesheet> It produces: 4 with the corrected version of your xml source (it was not well-formed): <groups> <group> <tables> <table index="1" /> <table index="2" /> </tables> <views> <view index="3" /> <view index="4" /> </views> </group> <group> <tables> <table index="1" /> </tables> <views> <view index="1" /> </views> </group> </groups> Hope this helped. Cheers, Dimitre Novatchev.

I've tried various axis expressions and can't seem to figure it out... I'd be happy with either: A. the ability to count the unique nodes (and I'll compare to count of all nodes) B. just knowing there are duplicates. Example: Within each group, the table and view indexes need to be unique. Data in first group is OK, the 'view' in the second group is a duplicate... <group> <tables> <table index="1"/> <table index="2"/> </tables/> <views> <view index="3"/> <view index="4"/> </views/> </group> <group> <tables> <table index="1"/> </tables/> <views> <view index="1"/> </views/> </group> __________________________________________________ Do You Yahoo!?
