title: python find tags in deep nodes xml
body: <p>I want to reach the "thirdDepth1" tag using python ElementTree library. Below is the simplified version. In my real xml its depth is dynamic. So can't reach it  with giving path, using find(),findall(), iterfind(). Any ideas?</p>
  
  <pre><code>&lt;root&gt;
      &lt;firstDepth1&gt;
          &lt;secondDepth1&gt;
              &lt;thirdDepth1&gt;thirdDepthVal&lt;/thirdDepth1&gt;
          &lt;/secondDepth1&gt;
      &lt;/firstDepth1&gt;
      &lt;firstDepth2&gt;
          &lt;secondDepth2&gt;&lt;/secondDepth2&gt;
      &lt;/firstDepth2&gt;
  &lt;/root&gt;
  </code></pre>
