How do I extract a background= value from a string containing HTML in JavaScript?
<p>I have a string containing HTML loaded from another page, how do I extract the background property from it's body tag using Javascript?</p>

<p>The body tag in the string looks like this:</p>

<pre><code>&lt;body onload='init();' background='storage/images/jsb_background.jpg' link='#000000' vlink='#000000' alink='#000000' leftmargin='0' topmargin='0' marginwidth='0' marginheight='0'&gt;
</code></pre>

<p>Thanks!</p>
