Create a key: <xsl:key name="anchor-by-id" match="anchor[parent::xref]" use="@id"/> Then for each anchor, count how many occurances are in the key: select="count(key('anchor-by-id', @id) > 1)" If there is more than one occurrance then the id is not unique. If you don't want an entry for each non-unique @id, then only generate output for the first occurrance: select="count(key('anchor-by-id', @id) > 1) && generate-id(.) = generate-id(key('anchor-by-id', @id)[1])" cheers andrew
