The SAX stuff is probably the biggest group of classes that hasn't been implemented but could be done easily.

Re: [PyKDE] XML support
Is anyone doing anything major with the qtxml package? Is XML support in PyQt experimental? Perhaps I would be better to rely on another package for now...I also see the none of the SAX stuff is wrapped or exposed. If qtxml was good enough, it'd be one less package I'd need to add to my project. I don't really know much about the Qt XML stuff, and even less about its support in PyQt. However, I have spent a bit of time recently looking into Python XML support. My conclusion is as follows: if you need basic XML support, the Python-supplied 'xml' package may well do what you need. It's based on the ubiquitous expat parser, so it's fast and robust. However, it's not a validating parser, and it doesn't have support for XPATH or XSLT. if you need those, go straight to 4Suite. State of the art stuff, designed and written for Python, with all the features you could ask for on a very fast 'C' based implementation. There's also the PyXML package which claims to be a drop in replacement for the standard 'xml' package. This works well enough and has a validating parser and full DOM Level 2 support. It has a dated XPATH implementation and buggy XSLT, plus it's slower than 4Suite, so it's hard to recommend it over 4Suite unless lightness is high amongst your priorities. Quite where that leaves qtxml I'm not sure. I'm not convinced it's a particularly worthy addition to Qt since XML libraries are complex and hard work to keep up to date. It's bound to be a lesser solution that any of the specific XML C++ packages out there like Xerces. A PyQt port of qtxml seems to make even less sense, since Python has an absolute abundance of top quality XML solutions. I appreciate your point about keeping the packages base of your application as simple as possible, but to be honest, if that's the best reason you have, installing 4Suite will be well justified. -- eatapple core dump ___ PyKDE mailing list[EMAIL PROTECTED] http://mats.imk.fraunhofer.de/mailman/listinfo/pykde
