I've done some work with ElementTree for CPSIO, and I haven't found it
very easy to use because of all the extra namespace URI, and xpath stuff
used for the tree navigation (xpath_findall, ..) which seem to get in
the way. Also it could be that I find the DOM approach easier since I'm
used to it in javascript already.
The iterparse approach is by far the mots pythonic approach ever (tm):
http://effbot.org/zone/element-iterparse.htm
Quoting the URL, here is the RSS-reader-in-less-than-eight-lines example
which is quite expressive:
"""
from urllib import urlopen
from cElementTree import iterparse
for event, elem in iterparse(urlopen("http://online.effbot.org/rss.xml";)):
if elem.tag == "item":
print elem.findtext("link"), "-", elem.findtext("title")
elem.clear() # won't need the children any more
"""
This combines the simplicity of the ElementTree data structure with the
possibility to stream-process your input in similar way to SAX, cleaning
the memory as you go.
