jquery 2 divs children comparison
<p>I have 2 elements ( div ) :</p>

<p><strong>I</strong>                                    </p>

<pre><code>&lt;div id="1"&gt;
 &lt;div &gt;
  &lt;img /&gt; &lt;img /&gt;
  &lt;span&gt; &lt;/span&gt;
   . 
   .
 &lt;div&gt;
 &lt;div&gt;
  &lt;p&gt;&lt;/p&gt;
  .
  .
 &lt;/div&gt; 
 .
 .
&lt;/div&gt;
</code></pre>

<p><strong>II</strong></p>

<pre><code>&lt;div id="2"&gt;
 &lt;div &gt;
  &lt;img /&gt;
  &lt;span&gt;&lt;/span&gt;
  &lt;h1&gt;&lt;/h1&gt;
  . 
  .
 &lt;div&gt;
 . 
 .
&lt;/div&gt;
</code></pre>

<p>both divs have <code>different number of child</code> and those child further have <code>different number of there subchilds</code>. <strong>My question</strong> is , i want to compare these 2 div and access all the unsimilar elements present in div#2 in comparison with div#1. How can i do this with using jquery methods and as efficient as possible?</p>
