I started with DOM processing, but the computer I had back then couldn't handle XML files larger that 60K or so. (Serious memory limitations.) So I learned SAX to extract data from my XML, but had to revert to DOM to put data back in. Since these worked differently, I ended up creating a DOM element, then passing the XML text back to a SAX parser. It was ugly, but I got around the file size.
I've replaced everything with ElementTree. I'm on a computer without memory limitations (well, I haven't tried to parse a file too large yet), and ElementTree does a good job of extracting information as well as writing human-readable XML. I think the ElementTree page has a good tutorial. It's good enough for me, at least. The only disadvantage I've run into is my implementation spends a lot of time parsing and over writing my XML data files, so that overhead is costly, but the application is small enough, and the network isn't getting bogged down, so I can get away with it. I've got some very old examples at this page: http://www.spiritone.com/~english/code/ims.html The code isn't well commented, but hey, this is Python : ) On 2/13/09, Neil Munro <neilmu...@gmail.com> wrote: -- Josh English joshua.r.engl...@gmail.com http://joshenglish.livejournal.com _______________________________________________ XML-SIG maillist - XML-SIG@python.org http://mail.python.org/mailman/listinfo/xml-sig
