Well, "bloat" is a word I would use for any DOM implementation.

lxml is actually quite the opposite of the three: extremely flexible, safe and

No. lxml will not support the DOM API. It already has a (mostly?) equivalent
API that is much simpler in spirit (and thus much easier to use), so there is
no reason for us to take the step back to the impressively un-pythonic DOM API.

If you really want a W3C-DOM compatible API and want to use libxml2, there is
a project that implements DOM on top of them: libxml2dom.


I assume this is for porting existing code? But even then, you may consider
rewriting the XML parts in lxml. We had a couple of comments on the list that
make me believe that this is a) not that hard (depending on your code
size/architecture) and b) worth it, at least in the cases I heard about.

Oh, and for the really hard-to-port stuff, you can still use Python's DOM support:
