Mark - fair enough: I acknowledge my unfamiliarity. My cries of pain were amplified by the fact that I couldn't do anything on the internet for a whole week apart from see emails by imposing on friends or using an expensive G3 connection. So I was trying to learn with inadequate materials. My priority now is to finish the very small program I've been working on without using XML, since it's so simple, but then to go back and see what I can learn. Clearly I am still struggling with the underlying model (a tree represented by a parenthetical structure? Seems a long way from a real tree - but that's just my ignorance, I realise).
I'm interested in your ability to parse xml files in order to determine the structure - my guess is that you must have a foolproof method of dealing with dead ends. In my small experiments I was surprised to see that some of the things I tried to do met with no result, not even an error message. Thanks for taking the time to reply.
