Thanks Michael, This has further been complicated by the fact that I have image ID's in the result set that are repeated..in what is essentially a de-normalised structure Eg. <results lastid="9"> <image> <id>37</id> <imagetitle>Fred</imagetitle> <imagelocation>fred.jpg</imagelocation> <imagesubject>Fred</imagesubject> </image> <image> <id>9</id> <imagetitle>Wilma</imagetitle> <imagelocation>wilma.jpg</imagelocation> <imagesubject>Wives</imagesubject> </image> <image> <id>9</id> <imagetitle>Wilma</imagetitle> <imagelocation>wilma.jpg</imagelocation> <imagesubject>Women</imagesubject> </image> <image> <id>9</id> <imagetitle>Wilma</imagetitle> <imagelocation>wilma.jpg</imagelocation> <imagesubject>Fred</imagesubject> </image> <image> <id>22</id> <imagetitle>Barney</imagetitle> <imagelocation>barney.jpg</imagelocation> <imagesubject>Bam Bam</imagesubject> </image> <image> <id>22</id> <imagetitle>Barney</imagetitle> <imagelocation>barney.jpg</imagelocation> <imagesubject>Betty</imagesubject> </image> <image> <id>24</id> <imagetitle>Dino</imagetitle> <imagelocation>dino.jpg</imagelocation> <imagesubject>Dino</imagesubject> </image> <image> <id>24</id> <imagetitle>Dino</imagetitle> <imagelocation>dino.jpg</imagelocation> <imagesubject>Fred</imagesubject> </image> </results> So what I have is a key on id at the top of my template: <xsl:key name="idkey" match="image" use="id"/> .. Then I want to output a line for each unique ID using: <xsl:for-each select="photographs::[count(. | key('idkey', id)[1])=1]"> .. Is there any way in the above line I can apply the restriction that the id must be in a sibling of the image with the @lastid so I only output items with id's of 22 and 24?
