This works well if the node sets are lying on the same level in the xml structure. But if I use something like this: for $doc in //text/body/(abstract | level/metadata1)[. &= 'searchTerm'] return $doc/../.. ... I either get the <text> or the <body> element as a result. But I always need the <text> element. Is it somehow possible to adjust the return statements in that it treats the results differently if they come from different node sets? I know it's possible to use if - clauses in the return statement but how would I specify the originating node sets? Thank you again, Peter -- 10 GB Mailbox, 100 FreeSMS/Monat http://www.gmx.net/de/go/topmail +++ GMX - die erste Adresse für Mail, Message, More +++
