title: Count all divs in a component having 'ng-show' attribute
body: <p>I have a component &lt;row/&gt; containing multiple &lt;cell/&gt; components.</p>
  <p>Some of the cells have ng-hide attr and some cells have a keyword 'mutate' :</p>
  <pre><code>&lt;row&gt;
     &lt;cell&gt; &lt;/cell&gt;
     &lt;cell ng-hide = &quot;cond&quot;&gt; &lt;/cell&gt;
     &lt;cell mutate&gt; &lt;/cell&gt;
  &lt;/row&gt;
  </code></pre>
  <p>Using <strong>$element.find(&quot;cell&quot;)</strong>, I'm able to get the count of all &lt;cell/&gt; within a &lt;row/&gt;.
  But, I want to find the the number of cells with &quot;mutate&quot; attr or number of cells with &quot;ng-hide&quot; attr. Finding either will do.</p>
  <p>Can someone please help me out here?</p>
