If the problem is that everything gets read in before anything gets written
out, Scott's answer is the right one:
set "http://xml.apache.org/xalan/features/incremental"; to true.
If the problem is that you're running out of memory... Scott's point about
the current limit on number of nodes per document, and my comment about
future work on pruning, both apply.
