Elements and Element Trees (effbot.org) 的简要使用

ElementTree

cElementTree

  • http://effbot.org/zone/celementtree.htm

  • 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
       ------------------------------------------------------------

    comparisions to other popular XML toolkits, and more, see:
