title: Use jQuery :has() and :contains() selectors together
body: <p>I have a list item element that contains a label element. I want to select the list item element with the <code>:has()</code> selector. Inside the label element there is text I want to match with <code>:contains()</code>. Is it possible to do both of these things with a single line of jQuery? If not, what is an elegant way to select the li element based on the contents of its child label element?</p>
  
  <pre><code>&lt;li&gt;
      &lt;!-- I want to select this one --&gt;
      &lt;label&gt;Label 1&lt;/label&gt;
      &lt;!-- more follows --&gt;
  &lt;/li&gt;
  </code></pre>
