     <p>This is the inverse of <code>:empty</code>. </p>
     <p>One important thing to note regarding the use of <code>:parent</code> (and <code>:empty</code>) is that child nodes include text nodes.</p>
     <p>The W3C recommends that the <code>&lt;p&gt;</code> element have at least one child node, even if that child is merely text (see <a href="http://www.w3.org/TR/html401/struct/text.html#edef-P">http://www.w3.org/TR/html401/struct/text.html#edef-P</a>). Some other elements, on the other hand, are empty (i.e. have no children) by definition:<code> &lt;input&gt;</code>, <code>&lt;img&gt;</code>, <code>&lt;br&gt;</code>, and <code>&lt;hr&gt;</code>, for example.</p>
