So, in order to implement the update problem originally mentioned in this thread, which language/API would I use in BaseX? - Godmar
I'm not sure what you mean with "implement the update problem"; if you want to bypass the current bug, you might try to create a simple document without namespace (<root/>), and add new nodes as children. The language you're using, or API, doesn't matter (as mentioned before, you'll have most freedom with our own API).
