• 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
