Python XML iterparse() namespacing

Question

According to this post , I successfully can parse my XML file, and reading it's content. However, if I add namespace to it, the whole thing goes wrong.

Let's consider the following XML:

<root xmlns="MyNamespace">
   <A1>
     <B1></B1>
     <C>1<D1></D1></C>
     <E1></E1>
   </A1>
   <A2>
      <B2></B2>
       <C>2<D></D></C>
       <E2></E2>
   </A2>
</root>

My iterparse looks like this:

context = ET.iterparse('../in/process/teszt.xml', events=('end', ), tag='B1')

I found several examples, but to be honest I don't really understand them, and have no idead how to solve this problem.

如果XML具有默认名称空间 ，则需要在tag使用名称空间URI以及元素的本地名称：

context = ET.iterparse('../in/process/teszt.xml', events=('end', ), tag='{MyNamespace}B1')
