Thanks for the comments! I know eXist I worked with it same years ago (in a Java context). I have done mapping of XML to relational and back myself and it can be tricky! FYI: I have a good document on the topic.

I think the best way forward is a RDBMS. It was probably a mistake in the first place to do it in XML. Especially since the files get relatively big and updates are necessary. Transactions are not an issue the application is stand alone.
