jQuery: find overlapping elements between two result sets
<p>If I had two jQuery result sets, say</p>

<pre><code>$("#someParent *")
</code></pre>

<p>and </p>

<pre><code>$("#someElement").nextAll()
</code></pre>

<p>then how could I best get all the elements that occur in <em>both</em> result sets?</p>
