Nothing beats an Internal binary format for processing speed. If you think about xml parsing, most of the time is spent searching for the closing tag. If these things are known internally (how far to jump to skip to the end tag) then processing time will obviously come down dramatically. but then again, it's possible to do xml in realtime, certainly in single network packets. So one would really only notice the benefit on todays machines when the size of the file goes over 1M. not to forget, xml is binary already. Everytime I do 'debug myfile.xml' I see all these hex codes - oh and yes, the characters are shown on the far right just in case. Harold seems to favour a bit of lightweight zipping/gzipping/bzipping to cut some weight off for on the wire transmission and I tend to agree with that. So my opinion is that binary xml is useful to have, should be done on the fly, but just as part of the loader function for putting it in memory. It's definitely a nice sort of optimisor technology for any high performance parser to have. David -- Computergrid : The ones with the most connections win.
