title: Convert a <span>'s text into a hyperlink
body: <p>UPDATE:<br />
  Answer #3 ended up working the best.  I most likely did something wrong with the other suggestions; #3 was maybe the easiest to implement.  If you are curious, the example solutions that I tried can be found here (for now):</p>

  <p>ORIGINAL POST:<br />
  I have a plain text website address inside a <code>&lt;span&gt;</code> tag.  I'd like to change that &lt;span&gt; tag into a proper hyperlink with <code>target="_blank"</code></p>
  
  <p>I've put together a detailed example of what I have to work with here: <a href="http://bit.ly/spantourl">http://bit.ly/spantourl</a></p>
  
  <p>If you don't want to click through, here is what I have:</p>
  
  <pre><code>&lt;span&gt;http://www.domain.com/about&lt;/span&gt;
  </code></pre>
  
  <p>and I need to change that into:</p>
  
  <pre><code>&lt;a href="http://www.domain.com/about" target="_blank"&gt;http://www.domain.com/about&lt;/a&gt;
  </code></pre>
