title: Exclude Item from Web-Scraped Loop
body: <p>Suppose I have the following <code>html</code>:</p>
  
  <pre><code>&lt;h4&gt;
       &lt;a href="http://www.google.com"&gt;Google&lt;/a&gt;
  &lt;/h4&gt;
  &lt;h4&gt;Random Text&lt;/h4&gt;
  </code></pre>
  
  <p>I am able to identify all <code>h4</code> headings via a loop such as:</p>
  
  <pre><code>for url in soup.findAll("h4")
      print(url.get_text())
  </code></pre>
  
  <p>And that works well except it includes the "random text" element of the <code>h4</code> heading.  Is it possible to programmatically remove occurrences of <code>h4</code> headings that do not meet a certain criteria - for example, those that don't contain a link?</p>
