jQuery, REAL :not operator equivalent?
<p>this code line select all the children inputs inside any div who his class name is not "id" and "quantity" ::</p>

<pre><code>$("div.item &gt; div:not(.id,.quantity) &gt; :input").live("keydown",function(event) {});
</code></pre>

<p><strong>what is the code line to do the opposite?</strong>, something like ::</p>

<pre><code>$("div.item &gt; div:filter(.id,.quantity) &gt; :input").live("keydown",function(event) {});
</code></pre>

<p>( of course <code>:filter</code> is not a valid jQuery selector )</p>
