[jdev] Help parsing incremental XML

[Dr. Craig Hollabaugh]

JD and Kevin,

SAX parsers parse as the stream comes in. Your code gets callbacks on a
tag by tag basis. A DOM parser creates a complete document to
manipulate. If you're parsing is really simple, you can use a regular
expression to find what you're looking for.
