Hi Rob, I've been using Xalan for conversion of a very large data set recently (several Gb's). I'm fully satisfied. I tried Saxon (too slow) and Sabletron (too many coredumps) as well, only Xalan did its job. My only problems were memory related, and I had a litte fuss with the recursion level. But all in all, it's definatly a winner - my advice is to not bother with any other tool. If Xalan cannot handle your task, I doubt that there are a lot of tools that can. Good luck, and thanks to the Xalan crew for a great implementation.
