title: how to get text from within a tag, but ignore other child tags
body: <p>I am working with beautiful soup.
  I have a html string:</p>
  
  <pre><code>&lt;div&gt;&lt;b&gt;ignore this&lt;/b&gt;get this&lt;/div&gt;
  </code></pre>
  
  <p>How do I retrieve "get this", while ignoring "<b>ignore this</b>"</p>
  
  <p>Thanks</p>
