Well, you could find all the rs with unique cat-nums, iterate through them and for each of them get all the rs with that cat-num: <xsl:for-each select="r[cat-num and generate-id() = generate-id(key('multiBooks',cat-num))]"> <xsl:sort select="cat-num" /> <xsl:variable name="bibno" select="bibno" /> <xsl:variable name="rs" select="key('multiBooks', cat-num)" /> ... </xsl:for-each> Then you can find those rs with the same cat-num whose bibno is not the same as the bibno of the first one with:: $rs[bibno != $bibno] (Of course you might get several rs with the same bibno returned by this, but you said you just wanted to know whether they were different from the first one, so I guess that's what you want. Otherwise, you need to do multiple-grouping.) Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
