one other thing to be aware of in this area... beware of libraries which claim to parse xml but choke on data greater than 64K. I started down that path quite happily until I ran into a large xml doc.. fortunately, for my app I could get away with a pre-process step to retrofit things without too much pain:
a) break the larger document down into smaller elements with simple string parsing b) store those smaller snippets into a db c) use the commercial library to parse and navigate those smaller pieces as needed during "runtime" the end result was one that met my needs for handling larger documents and, while there was an up-front hit in parsing thru the doc, because this document was updated relatively infrequently, using the db/xml combo produced a faster and more manageable data set than relying on the library to process the large document each time. I confined my dependence on the xml library to relatively small chunks - it is quite capable of handling them in a speedy fashion. Arguably an ugly solution to an xml purist, but works and allows me to process an arbitrarily large xml document in a reliable fashion.
