title: jQuery selectors on custom data attributes using HTML5
body: <p>I would like to know what selectors are available for these data attributes that come with HTML5.</p>
  
  <p>Taking this piece of HTML as an example:</p>
  
  <pre><code>&lt;ul data-group="Companies"&gt;
    &lt;li data-company="Microsoft"&gt;&lt;/li&gt;
    &lt;li data-company="Google"&gt;&lt;/li&gt;
    &lt;li data-company ="Facebook"&gt;&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>Are there selectors to get:</p>
  
  <ul>
  <li>All elements with <code>data-company="Microsoft"</code> below <code>"Companies"</code></li>
  <li>All elements with <code>data-company!="Microsoft"</code> below <code>"Companies"</code></li>
  <li>In other cases is it possible to use other selectors like "contains, less than, greater than, etc...".</li>
  </ul>
