Do you need to optimize communication (bytes sent/received) or
CPU (time spent parsing)?

If it is communication, try compressing the XML with a standard
algorithm. See the "content-coding" part of HTTP 1.1 for some
samples.

If it is CPU, benchmark XML parsers. Also, use an event-based
parser (SAX) to build your data structures directly. With a
DOM-based parser, you will build objects twice -- once for
the DOM and once for your application.
