title: Complex Beautiful Soup query
body: <p>Here is a snippet of an HTML file I'm exploring with Beautiful Soup.</p>
  
  <pre><code>&lt;td width="50%"&gt;
      &lt;strong class="sans"&gt;&lt;a href="http:/website"&gt;Site&lt;/a&gt;&lt;/strong&gt; &lt;br /&gt; 
  </code></pre>
  
  <p>I would like to get the <code>&lt;a href&gt;</code> for any line which has the <code>&lt;strong class="sans"&gt;</code> and which is inside a <code>&lt;td width="50%"&gt;</code>.</p>
  
  <p>Is it possible to query a HTML file for those multiple conditions using Beautiful Soup ?</p>
