ElementHandler!
Register some handlers to your elements, and just deal with the subtrees
as they flow in.
You can detach as you go. So, you actually are processing the doc as
it's read, pretty much, plus you're given the ability, if you app
can process sequentially, of releasing the subtrees when you're done
with them, freeing memory.
