使用python minidom解析属性时出错

Question

我的xml文件中有一个这样的结构:

<questions>
    <q question="Where were Jim and his mother going?" answer="The school"/>
    <q question="What color was the ball?" answer="orange"/>

我正在尝试用python中的minidom解析它

questionsblock = s.getElementsByTagName('questions')    
questions = questionsblock[0].getElementsByTagName('q')
counter = 1
for q in questions:
    question = q.attributes['question'].value
    answer = q.attributes['answer'].value

，我得到这个错误:

File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/dom/minidom.py", line 524, in __getitem__
KeyError: 'answer'

我在这里错过了什么?

Answer 1

从你发布的代码中我可以看出，绝对没有任何问题。

但是，考虑到您提供的XML只是一个摘录，并且没有显示</questions>结束标记，我怀疑可能在某个地方有一个缺少answer属性的q元素。
