Display RSS Image with SimplePie

Question

I'm setting up a page which grabs the first entry from multiple RSS feeds. I'm running into a lot of RSS feeds that are formated differently. I'm using SimplePie to parse the feeds. The current feed I'm trying to grab the image from is below:

<entry>
<updated>2011-01-28T09:00:00Z</updated>
<title><![CDATA[Information on Title of Product]]></title>
<link href="http://link-to-website"/>
<summary type="xhtml">
<div xmlns="http://www.w3.org/1999/xhtml">
<img src="http://image.JPG"/>
<div>Title of Image</div>
</div>
</summary>
</entry>

How can I grab the img tag from within the summary tag with SimplePie so I can display this on my website?

Thanks in advance.

You will have to grab the content from with SimplePie, and then run it through and XML parser (such as SimpleXML, to get the node you want). For example:

$summary = <<<XML
<div xmlns="http://www.w3.org/1999/xhtml">
    <img src="http://image.JPG"/>
    <div>Title of Image</div>
</div>
XML;

$xml = new SimpleXMLElement($summary);
$imageSrc = (string) $xml->img->attributes()->src;

Didn't use SimpleXML for quite some time, but it should be something like that.
