If > at the end > nothing is found, DO SOMETHING DIFFERENT...... See my reply to "RE: [xsl] [Fwd: CLARIFICATION IN XML 2 XML TRANSFORMATION]", that contains a solution to a similar problem. What you need is to write a recursive template that tokenizes using COMMA as a delimiter, then on each token check if that appears in the other list, e.g. with contains(concat(',', elem1, ','), concat(',', $token, ',')). You can find more info on recursive templates in the FAQ. Cheers, Jarno
