title: Replace html entities with the corresponding utf-8 characters in Python 2.6
body: <p>I have a html text like this:</p>
  
  <pre><code>&amp;lt;xml ... &amp;gt;
  </code></pre>
  
  <p>and I want to convert it to something readable:</p>
  
  <pre><code>&lt;xml ...&gt;
  </code></pre>
  
  <p>Any easy (and fast) way to do it in Python?</p>
