Select elements from jQuery selection
<pre><code>&lt;div class="a b"&gt;&lt;/div&gt;
&lt;div class="a c"&gt;&lt;/div&gt;
&lt;div class="a b"&gt;&lt;/div&gt;
&lt;div class="a c"&gt;&lt;/div&gt;
&lt;div class="a b"&gt;&lt;/div&gt;
&lt;div class="a f"&gt;&lt;/div&gt;


var selection = jQuery('div.a');
</code></pre>

<p>Does anybody know a way to select divs with class="b" from <code>var selection</code>
without iterating through array's elements and checking their class one by one?</p>
