effbot.org proudly presents release 0.9.8 of the cElementTree library,
a fast and very efficient implementation of the ElementTree API, for
Python 2.1 and later. On typical documents, it's 15-20 times faster
than the Python version of ElementTree, and uses 2-5 times less
memory.
Here are some benchmark figures, using a number of popular XML tool-
kits to parse a 3405k document-style XML file from disk:
library memory time
------------------------------------------------------------
amara 20300k 6.4s
minidom (python 2.4) 53000k 1.4s
ElementTree 1.2.4 14500k 1.1s
cDomlette 20500k 0.54s
pyRXPU 10850k 0.175s
libxml2 16000k 0.098s
cElementTree 0.9 4900k 0.047s
------------------------------------------------------------
readlines (read as utf-8) 8850k 0.093s
readlines (read as ascii) 5050k 0.032s
------------------------------------------------------------
This release also includes a new "iterparse" mechanism, which can be
used to process the tree as it is being built. While not quite as
fast as a full parse, it's over 4 times faster than Python's standard
SAX interface, and even a bit faster than sgmlop.
The library is available as C source code, and as Windows installers
for all recent Python versions. Get your copy here:

The cElementTree module uses some support functions from the standard
ElementTree library, and will not work properly without it. If you
haven't installed it already, you can get it from:
