Thanks for the info!
For a multi-gigabyte file, I would still recommend C/C++, because the processing code which sits on top of the XML library needs to be Python, and that could turn out to be a significant overhead in such extreme cases. Of course, the exact strategy to follow would depend on the specifics of the case, and all this speculation may not really apply! :) Regards Sreeram
