If your transformation is serial, then a SAX application will certainly be
much faster, as you don't have to build the tree in memory (the tree for a
50Mb file will be vast).

You might like to look at Saxon's "preview mode" if you want an XSLT
solution, this essentially does an XSLT transform on one subtree at a time,
avoiding the need to build the complete tree in memory.
