How to select an element from a string value
<p>I have <a href="http://jsfiddle.net/PSV4F/" rel="nofollow">this</a> code :</p>

<pre><code>&lt;div id="example"&gt;
    Hello
&lt;/div&gt;

var string="example";
alert($(''+string).html());
</code></pre>

<p>but it should print "Hello" not null...why?</p>
