title: XML Parsing: Element Tree (etree) vs. minidom
body: <p>I've been using minidom to parse XML for years. Now I've suddenly learned about Element Tree. My question which is <em>better</em> for parsing? That is:</p>
  
  <ul>
  <li>Which is faster?</li>
  <li>Which uses less memory?</li>
  <li>Do either have any O(n^2) dependencies I should worry about?</li>
  <li>Is one being depreciated in favor of another?</li>
  </ul>
  
  <p>Why do we have two interfaces?</p>
  
  <p>Thanks.</p>
