未封閉的XML令牌

Question

我將如何處理Python 2.6中的這個錯誤？

Traceback (most recent call last): 
    File "./fetch_xml_collect.py", line 32, in <module> 
    tree=ET.parse(response) 
    File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xml/etree/ElementTree.py", line 862, in parse 
    tree.parse(source, parser) 
    File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xml/etree/ElementTree.py", line 587, in parse 
    self._root = parser.close() 
    File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xml/etree/ElementTree.py", line 1254, in close 
    self._parser.Parse("", 1) # end of data 
xml.parsers.expat.ExpatError: unclosed token: line 56, column 1 

當前代碼正在實施：

while urlget==1: 
     try: 
       response = urllib.urlopen(rep) 
     except IOError: 
       print("reason") 
     else: 
       try: 
         tree=ET.parse(response) 
       except IOError: 
         print("XML Parse Error\n") 
       else: 
         root=tree.getroot() 
         print root[0].text 
         powerlist=tree.findall('meter/power') 
         print powerlist[0].tag,powerlist[0].text 

的問題是：我怎麼會在給定的代碼處理上述錯誤？

Answer 1

try: 
    #Some code 
    ... 
except xml.parsers.expat.ExpatError, ex: 
    print ex 
    continue 

像上面這樣的東西應該工作。只要continue，如果你得到這個錯誤。它將繼續進行循環的下一次迭代，或者如果它是最後一次迭代，則跳出循環。

XML形式不正確，無法處理。只需跳過它並繼續下一個。
