   Re: [xml-dev] Merge xml documents with SAX

[ Lists Home | Date Index | Thread Index ]

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: 
(or in the distribution as 
build/extras/org/jibx/extras/DocumentComparator.java). If your documents 
use ordering doing a merge should be easy.
