In general yes, the main problem will be preceding search. If your input is smallish you may get away with just changing preceding to preceding-sibling which would help the performance somewhat. The better solution would to be create key over the vform elements using Category as the key value. You can then use key() & generate-id() to test if a given vform is the first with that Category value. Something like this (untested), <xsl:key name="vformByCategory" match="vform" use="Category"/> <xsl:for-each select="/Search/SearchResults/vform"> <xsl:if test="generate-id(.)= generate-id(key('vFormByCategory',Category)[1])"> <!-- Do something --> </xsl:if> </xsl:for-each> Kev.
