If it's so bad that you'd tell someone not to use it, why isn't it deprecated?
Because it would take a lot of work to deprecate, and there are a lot of other things people are working on that are deemed more important.
Also because there isn't a complete consensus on how terrible it is. If you are doing advanced XML processing, it definitely isn't the best choice, because it's missing a bunch of features and it has some idiosyncratic behavior. However, it is conveniently available without adding another dependency and it supports simple use-cases OK; this is still a problem with other XML libraries in Python, especially DOM libraries. (For example, incompatibilities between the various lxml implementations.)
Here's an example of a behavior it has which probably isn't going to change any time soon:
>>> from twisted.web.microdom import parseString >>> s = '<div><span>hello</span> <span>world</span></div>' >>> parseString(s).toxml() '<?xml version="1.0"?><div><span>hello</span><span>world</span></div>' >>>
So if you need such advanced XML features as correct whitespace handling, steer clear. ;)
