这不漂亮，但它应该可行...

This isn't pretty, but it should be workable ...

ParseError = xml.parsers.expat.ExpatError if sys.version < (2, 7) else xml.etree.ElementTree.ParseError

try:
    ...
except ParseError:
    ...

您可能需要根据版本修改您导入的内容（或捕获从 xml 导入各种子模块，如果它们不存在于python2.6上，那么导入错误 - 我没有安装该版本我现在不能做一个强大的测试...）

You might need to modify what you import based on versions (or catch ImportError while importing the various submodules from xml if they don't exist on python2.6 -- I don't have that version installed, so I can't do a robust test at the moment...)
