2005年发布 cElementTree C内核的 ElementTree

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
   ------------------------------------------------------------
