title: Protractor find element inside a repeater
body: <p>Below is my markup</p>
  
  <pre><code>&lt;tr ng-repeat="post in posts"&gt;
    &lt;td ng-click="activePost(post)" class="title"&gt;{{post.title}}&lt;/td&gt;
    &lt;td&gt;&lt;button class="btn btn-danger" ng-click="delete(post)"&gt;Delete&lt;/button&gt;
    &lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>I'm trying to get the element with the <code>title</code> class.</p>
  
  <p>The code I use to access the repeater is:</p>
  
  <pre><code>postsList = element.all(by.repeater('post in posts'));
  </code></pre>
  
  <p>Is there a way to get the element by doing something like the following in jQuery:</p>
  
  <pre><code>var titleText = $("tr:first").find(".title").text();
  </code></pre>
  
  <p>Is there a way of doing something similar to this with protractor? </p>
