title: xml.etree.ElementTree getElementByID()?
body: <p>How to get the equivalent of <code>getElementByID()</code> with the Python library <code>xml.etree.ElementTree</code>?</p>
  
  <p>There seems to be a method called <code>parseid()</code> but my tree is already parsed. I don't want to parse it again.</p>
