If you're working in Java, instead of building your own tree you might
want to take a look at Don Park's SAXDOM:

  http://www.quake.net/~donpark/saxdom.html

Neither the DOM nor SAX is finalised yet (though SAX is closer), and I
haven't had a chance to test Don's package yet, but there are still a
couple advantages to avoiding a proprietary tree structure:

1) You will have to make fewer changes later on.

2) Since Don's package uses SAX, your code will work with any
   supported parser rather than just Microsoft's (currently, there are
   SAX drivers for NXP, Lark, AElfred, XP, _and_ MSXML); eventually,
   it will work for any parser with DOM support as well.


All the best,


David
