title: How to get all sub-elements of an element tree with Python ElementTree?
body: <p>I want to find a way to get all the sub-elements of an element tree like the way <code>ElementTree.getchildren()</code> does, since <code>getchildren()</code> is deprecated since Python version 2.7.<br />
  I don't want to use it anymore, though I can still use it currently.</p>
