Hello: We're trying to grab the page XHTML each time the user presses save. Unfortunately, when we run cURL within hook_entity_update, we are getting old values. Sample code is below. Can someone suggest how to get the latest page source, not some cached value, just after the user presses "save"? Thanks, Joe function pyrdfa_entity_update($node){ if ($node->type=="article"){ drupal_set_message('pyrdfa_entity_update hook invoked!'); // Extract RDF metadata $ws_endpoint = "http://www.w3.org/2007/08/pyRdfa/extract?uri="."http://beta.planetmath.org/".$node->uri['path']; $returnXML = curl_post($ws_endpoint); // this will display OLD metadata drupal_set_message('<h2>Returned RDF/XML</h2><pre>'. htmlspecialchars($returnXML) .'</pre>'); } }
