title: Get inner text from lxml
body: <p>lxml.html.fromstring insists on wrapping up everything in a tag (<code>p</code> default). From this tag tree,</p>
  
  <pre><code>&lt;p&gt;this is &lt;b&gt;the&lt;/b&gt; good stuff&lt;p&gt;
  </code></pre>
  
  <p>I want to extract the string:</p>
  
  <pre><code>this is &lt;b&gt;the&lt;/b&gt; good stuff
  </code></pre>
  
  <p>How do I do this?</p>
