Use .unwrap to unwrap the children of all divs with a specified class
<p>Is there a way to use the <code>.unwrap</code> function to unwrap all instances of a specific class (in this case 'blah')</p>

<pre><code>&lt;div class="blah"&gt;
  &lt;a href="http://google.com"&gt;Google&lt;/a&gt;
&lt;/div&gt;

&lt;div class="blah"&gt;
  &lt;span&gt;Testing&lt;/span&gt;
&lt;/div&gt;
</code></pre>

<p>Right now, I'm using a code like this:</p>

<p><code>$('.blah a').unwrap();</code></p>

<p>But this wouldn't unwrap the second piece of code with the <code>span</code> in it above.</p>
