I don't have enough experience with XML data. I spent hours trying to convert the XML response to a PHP object or array, but without any success.

I need to read all PropertyResults.

PHP Code:

$xml = simplexml_load_string($soap_xml_result);

$xml->registerXPathNamespace('soap', 'http://schemas.xmlsoap.org/soap/envelope/');
$xml->registerXPathNamespace('xsi', 'http://www.w3.org/2001/XMLSchema-instance');
$xml->registerXPathNamespace('xsd', 'http://www.w3.org/2001/XMLSchema');

$test = (string) $xml->Body->SearchResponse->SearchResult->SearchURL;
var_export($test);

Answer 1

Another solution, the only solution that worked for me :

$xml = $soap_xml_result;
$xml = preg_replace("/(</?)(w+):([^>]*>)/", '$1$2$3', $xml);
$xml = simplexml_load_string($xml);
$json = json_encode($xml);
$responseArray = json_decode($json, true); // true to have an array, false for an object
print_r($responseArray);

Enjoy :)
