title: How to find recursively for a tag of XML using LXML?
body: <pre><code>&lt;?xml version="1.0" ?&gt;
  &lt;data&gt;
      &lt;test &gt;
          &lt;f1 /&gt;
      &lt;/test &gt;
      &lt;test2 &gt;
          &lt;test3&gt;
           &lt;f1 /&gt;
          &lt;/test3&gt;
      &lt;/test2&gt;
      &lt;f1 /&gt;
  &lt;/data&gt;
  </code></pre>
  
  <p>Using lxml is it possible to find recursively for tag " f1 "? I tried findall method but it works only for immediate children.</p>
  
  <p>I think I should go for BeautifulSoup for this !!!</p>
