用php获取[cdata]内容

Question

I am reading this tutorial on fetching RSS feeds using PHP Simple XML.
Reason I wanna do it myself instead of Wordpress plugin is because of lack of displaying images.
Using this tutorial I thought I was going to be able to go through nodes myself and display what I want but I am not even fetching data I need because it is enclosed within ![CDATA]:

So I am after that img tag, but it's not there using this code from tutorial:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://rss.linksynergy.com/promo.rss?promoid=3076&token=8c86517642801a8d4e1132xxxxxxxxxxxxxxxx35e66a3');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);

$xml = new SimpleXMLElement($data);

Any suggestions welcome.

Thanks!

Answer 1

Try this:

$xml = new SimpleXMLElement($data, LIBXML_NOCDATA);

This will parse CDATA-Elements into normal text nodes so you can access them like any other text with $xml['decription']

See http://www.php.net/manual/en/simplexmlelement.construct.php for reference.
