Something > to investigate... Now you're trying to bind yourself to the XSLT processor implementation, which in my oppinion is the worst thing you can do. I understand that at least you can design the structure of the XML documents. Considering this, your options are: 1. live with the fact that your system can be extremely slow - advantage: you don't need to do anything - disadvantage: your solution is at least not scalable; worst case: it might not be usable at all 2. split your data through different XML files - advantage: it will work, with a proper design - disadvantage: it is harder/annoying to manipulate more than one file. If you are not careful in designing your solution, you will end up loading all files in one transformation step. 3. find the desired XSLT processor. - advantage: it will solve your solution cheap - disadvantage: probably you won't find it anyway. Still it will not work if you don't carefully desing the structure of the XML. You will be tightly bound to the XSLT processor ===== Marian http://www.utdallas.edu/~mgo031000/ __________________________________ Do you Yahoo!?
