effbot.org proudly presents 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.
The 0.9.2 release is 10-20% faster than 0.8 on my benchmarks, and uses
5-15% less memory.
Here are some benchmark results, using a number of popular XML tool-
kits to parse a 3405k source file on my development machine:
library memory time
------------------------------------------------------------
minidom (python 2.1) 80000k 6.5s
minidom (python 2.4) 53000k 1.4s
ElementTree 1.3 14500k 1.1s
cElementTree 0.8 5700k 0.058s
cElementTree 0.9 4900k 0.047s
------------------------------------------------------------
readlines (read as utf-8) 8850k 0.093s
readlines (read as ascii) 5050k 0.032s
------------------------------------------------------------
