xml.sax.xmlreader and expat

[Gary Robinson]

Hi,

We're using xml.sax.xmlreader in our app (http://www.goombah.com, which
is written in Python).

In Python 2.3.x, does that use the C-language expat under the hood? The
reason I'm asking is because we're wondering if we can speed up the
parsing significantly.

Thanks in advance for any input anyone can give.

Gary

if you want speed, you don't really want any of the xml.sax or xml.dom
stuff. I'm a bit biased, but I'd recommend the iterparse interface to
cElementTree:

or to lxml (if you want to do more than just parsing):
