title: jquery traversing to find a parent's parent
body: <p>HTML:</p>
  
  <pre><code>&lt;li class="comment"&gt;
  &lt;div class="p_comm"&gt;
   &lt;div class="avatar"&gt;&lt;img src="/img/1.jpg"&gt;&lt;/div&gt;
   &lt;div class="c_auth"&gt;author&lt;a class="del" title="delete it!" rel="19"&gt;x&lt;/a&gt;&lt;/div&gt;
   &lt;div class="c_cont w"&gt;what ever&lt;/div&gt;
   &lt;div class="c_time"&gt;12-23 13:22:15&lt;/div&gt;
  &lt;/div&gt;
  &lt;/li&gt;
  </code></pre>
  
  <p>I want to find the parent li relative to the <code>&lt;a&gt;</code> in this section. I can't find a function to do this. I've tried <code>prev(),parentsUntil()</code> none of them can do this. Currently i have to use <code>$(this).parent().parent().parent()</code> to reach <code>&lt;li&gt;</code>. Is there a function to find parent <code>&lt;li&gt;</code> directly?</p>
