$dom_obj = new DOMDocument();
$dom_obj->loadHTML($page_content);
$meta_val = null;

foreach($dom_obj->getElementsByTagName('meta') as $meta) {

Re: PHP and <txp:custom_field />

Did It)

<txp:php>
$page_content = file_get_contents(custom_field(array(‘name’ => ‘filed’)));
$dom_obj = new DOMDocument();
$dom_obj->loadHTML($page_content);
$meta_val = null;

foreach($dom_obj->getElementsByTagName(‘meta’) as $meta) {

if($meta->getAttribute(‘property’)==‘og:image’){

$meta_val = $meta->getAttribute(‘content’); } } echo $meta_val; </txp:php>
