Question

I am trying to extact the IMG SRC value out of the below RSS feed (only partial feed below).

I am currently using XML parser to get the rest of the items – which works fine (e.g.):

foreach($xml['RSS']['CHANNEL']['ITEM'] as $item) 
{
...

            $title = $item['TITLE'];
            $description = $item['DESCRIPTION'];
            $link = $item['LINK'];
        $desc_imgsrc = <how do i get this for below RSS feed??>;
...
}

However – how do i get the IMG SRC value from below RSS feed into a PHP variable? Specifically i am trying to extact “http://thumbnails.—.com/VCPS/sm.jpg” string into $desc_imgsrc variable above? How can i adapt above code to do that? Thanks.

Answer 1

This is HTML (XML) inside an XML CDATA element. CDATA (character data) is not parsed by the XML parser. You need to extract the value the same way you did with the other elements. Then you can parse the element value, either by using a regular expression or even better use an XML parser again (if the HTML data is valid XML).
