That doesn't seem to be a Xalan question; you'd be better off asking in a general XML users' mailing list.
Some database products now have XML support, and there are tools specifically marketed as "XML databases". It sounds like what you want is a "make"-like layer running on top of that to notice when source/style documents have been updated and regenerate the products, either immediately or when they're called for. ______________________________________ Joe Kesselman / IBM Research
