I'll second the vote for a pull parser approach. I've got a simple pull 
parser document comparison implementation as part of my JiBX project 
that might serve as a good starting point for this: 
http://cvs.sourceforge.net/viewcvs.py/*checkout*/jibx/jibx/build/extras/org/jibx/extras/DocumentComparator.java?content-type=text%2Fplain&rev=1.1 
(or in the distribution as 
build/extras/org/jibx/extras/DocumentComparator.java). If your documents 
use ordering doing a merge should be easy.
