title: ImportError: No module named xml.dom.minidom
body: <p>I try to export xml.dom to my python program. </p>
  
  <pre><code>from xml.dom import minidom
  </code></pre>
  
  <p>But when i run the code, i got this error:</p>
  
  <pre><code>import xml.dom.minidom
  ImportError: No module named xml.dom.minidom
  </code></pre>
  
  <p>This happened before when i rename my file to xml.py, but it's clear when i change name to other. But this is another problem i got. i didn't rename my file. It happened after i run apt-get update and apt-get upgrade ubuntu.</p>
  
  <p>What's wrong? </p>
