我一直试图解析一个文件xml.etree.ElementTree:

import xml.etree.ElementTree as ET
from xml.etree.ElementTree import ParseError

def analyze(xml):
    it = ET.iterparse(file(xml))
    count = 0
    last = None

    try:        
        for (ev, el) in it:
            count += 1
            last = el

    except ParseError:
            print("catastrophic failure")
            print("last successful: {0}".format(last))

    print('count: {0}'.format(count))

这当然是我的代码的简化版本,但这足以打破我的程序.如果删除try-catch块,我会在某些文件中出现此错误:

Traceback (most recent call last):
