The sirens have lured you!

I have a lot of experience with storing parsed document
trees in an object database and I have experimented with
storing the Java serialization of DOM-like models on disk,
and for what it's worth, in both cases retrieving the
document takes a lot longer than reparsing original XML. The
main reason is simply that there are more bytes to read.

The only technique that I find really effective for handling
large documents is to split them up into lots of small ones.
That way you only parse the bits the user actually wants to
