在python中识别损坏的.xml

我有一个小python脚本，它正在读取几个.XML文件。现在我必须声明，这些.XML文件没有以任何方式损坏。我怎么检查这个？我阅读它们的方法是：

xml_tree = ET.parse(path) //path = path to .xml
xml_file = xml_tree.getroot()

ET.parse（）

如果XML文件损坏，则引发

ParseError

异常：

>>> print open('test.xml').read()
This is not an XML file

>>> from xml.etree import ElementTree as ET
>>> ET.parse('test.xml')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/mj/Development/Library/buildout.python/parts/opt/lib/python2.7/xml/etree/ElementTree.py", line 1182, in parse
    tree.parse(source, parser)
  File "/Users/mj/Development/Library/buildout.python/parts/opt/lib/python2.7/xml/etree/ElementTree.py", line 656, in parse
    parser.feed(data)
  File "/Users/mj/Development/Library/buildout.python/parts/opt/lib/python2.7/xml/etree/ElementTree.py", line 1642, in feed
    self._raiseerror(v)
  File "/Users/mj/Development/Library/buildout.python/parts/opt/lib/python2.7/xml/etree/ElementTree.py", line 1506, in _raiseerror
    raise err
xml.etree.ElementTree.ParseError: syntax error: line 1, column 0

如果XML已损坏，

ET.parse（）

将引发异常。

try:
    ET.parse(path)
except ET.ParseError:
    print('{} is corrupt'.format(path))
