title: jQuery closest with attribute filter
body: <p>Does jQuery 1.5.1 support attribute selectors in the closest method?</p>
  
  <p>Given the structure below, <code>el</code> represents the checkbox with the value 513, and I'm trying to reach up and check the ancestor checkbox with the value of 0 with</p>
  
  <pre><code>$(el).closest("input[value='0']")[0].checked = true;
  </code></pre>
  
  <p>but the selector is returning nothing.</p>
  
  <p>Am I missing something silly?</p>

  <p><strong>EDIT</strong></p>
  
  <p>Sigh, so the checkbox with value 0 isn't an ancestor to <code>el</code>, just a sibling of the <code>ul</code> ancestor.  I got it to work with</p>
  
  <pre><code>$(el).closest("ul").siblings("input[value='0']")[0].checked = true;
  </code></pre>
  
  <p>But us there a cleaner way to grab it?</p>
