title: How convert the things before <br> to text?
body: <p>I'd like to use <code>lxml</code> to convert the thing before <code>&lt;br&gt;</code> of an element to string. Supposed the following <code>p</code> element is retrieved by <code>xpath()</code>, could anybody show me the comment to convert the thing before <code>&lt;br&gt;</code> to text (<code>xxx yyy</code> in this case)?</p>
  
  <pre><code>&lt;p&gt;&lt;span&gt;&lt;strong&gt;xxx&lt;/strong&gt;&lt;/span&gt; &lt;strong&gt;yyy&lt;/strong&gt;&lt;br&gt; &lt;span&gt;&lt;img alt="" class="content-image content-image-right" src="yyy.jpg"&gt;&lt;/span&gt;zzz&lt;/p&gt; 
  </code></pre>
