Use JDOM. You'll get more sleep, or you'll get to stay up later hacking
on JDOM (Jason, you know what I mean!)

I'm using JDOM to parse files upto 1MB in size, and JDOM is more than
capable of handling that amount of data.

Plus, JDOM is only ever going to get lighter and faster and more 
efficient as time goes on, and you'll get that for free. If you go
down the SAX route, it'll be upto you to ensure that it always works.

Well, you can't extend SAXHandler because it's package protected, and
I'm not sure that making it public is a Good Thing (TM).

Either delete the unrequired data after the Document is parsed, or
just live with the extra memory usage.
