Grab what's at:
http://home.pacbell.net/david-b/xml
and take a look. I think three classes may be of interest:
- org.brownell.xml.DomBuilder ... using your choice of DOM
implementations (Sun, IBM, Oracle, etc) this builds the
DOM tree using any SAX (or SAX2 alpha) parser.
- org.brownell.xml.DomParser2 ... walks a DOM tree and
emits a stream of SAX2 (alpha) events (SAX 1.0 being a
strict subset)
- org.brownell.xml.EchoHandler ... given a stream of SAX
(or, better, SAX2 alpha) events, writes out the XML.

See the above. It uses DOM for the intermediate representation, and
lets you pick your favorite SAX parser(s).
