Hi, If you are choosing which transform to perform next, then it's not really a chain. If it was a chain of transformations, then the surely the next transform to perform at any given time is by definition the next in the chain. What I think you may be after is to use a DOM result, query that with xpath, and then pass that as the input to whichever transform you choose to perform next. Cheers andrew
