title: Select item in unordered list and remove attribute
body: <p>I have a jquery script that adds a rel to all footer links:</p>
  
  <pre><code>$('#lp_footer a').attr('rel', 'pop');
  </code></pre>
  
  <p>My footer is an unordered list. I would like to select a certain link from the list and add a new rel attribute.
  How is that done?</p>
  
  <p>Sample HTML markup:</p>
  
  <pre><code>&lt;div id="footer"&gt;
    &lt;div class="inner_wrap"&gt;
          &lt;ul&gt;
              &lt;li&gt;&lt;a href="home.html" rel="pop"&gt;Home&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="about.html" rel="pop"&gt;about&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="contact.html" rel="pop"&gt;Contact&lt;/a&gt;&lt;/li&gt;
         &lt;/ul&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I would like to target the 2nd item in the list (about) and change the rel attribute.</p>
