It contains this CDATA tag which cannot be parsed with xml parser. if I

echo $test->description;

I see the img in the browser, but I cannot access the src in the script. Any idea how to do it??

Answer 1

You can not access XML inside CDATA section as XML.
You need to parse it with regular expression to fetch the src .
Or open it as another XML.

Tested & works:

$h = '<img src="http://images.24ur.com/media/images/210/Nov2012/61090877.jpg" alt="24ur.com"/>';

preg_match("/http:\/\/(.*?)[^\"']+/", $h, $matches);
var_dump($matches[0]);

Outputs:

string(60) "http://images.24ur.com/media/images/210/Nov2012/61090877.jpg" 

Answer 2

The description contains a single text node (the data of which is a piece of HTML). It doesn't contain any XML elements.

If you want to extract data from the HTML, you need to pass the data of the text node through an HTML parser first.
