 to just extract the first match. You should then be able to extract the attribute as in your code using the resultant element...
$xml2 = simplexml_load_string($result); $xml2->registerXPathNamespace("ns1","http://3e.pl/ADInterface"); $response = $xml2->xpath("//ns1:StandardResponse"); echo (string) $response['RecordID'];
