PHP: SimpleXML->xpath() not working correctly

It has to do with the namespace and document types not being set properly, so xpath() doesn't know how to parse it.

If you're only after a quick and dirty way of parsing (X)HTML, then all you need is to load it into a DOMDocument to create the SimpleXML object.

view sourceprint?

01.$contents = @file_get_contents($url);

02. 

03.if (!$contents) {   echo "Error for some reason.";

04.  return;

05.}

06. 

07.// Parse the document

08.$doc = new DOMDocument();

09.$doc->strictErrorChecking = FALSE;

10.$doc->loadHTML($contents);

11. 

12.$xml = simplexml_import_dom($doc);

13. 

14.foreach ($xml->xpath('//img') as $image) {

15.  $images[] = (string)$image['src'];

16.}
