You can use this (based on: http://php.net/manual/en/book.dom.php#93717);

function xml_to_array($root) {
    $result = array();

    if ($root->hasAttributes()) {
        $attrs = $root->attributes;
        foreach ($attrs as $attr) {
            $result['@attributes'][$attr->name] = $attr->value;
        }
    }

    if ($root->hasChildNodes()) {
        $children = $root->childNodes;
        if ($children->length == 1) {
            $child = $children->item(0);
            if ($child->nodeType == XML_TEXT_NODE) {
                $result['_value'] = $child->nodeValue;
                return count($result) == 1
                    ? $result['_value']
                    : $result;
            }
        }
        $groups = array();
        foreach ($children as $child) {
            if (!isset($result[$child->nodeName])) {
                $result[$child->nodeName] = xml_to_array($child);
            } else {
                if (!isset($groups[$child->nodeName])) {
                    $result[$child->nodeName] = array($result[$child->nodeName]);
                    $groups[$child->nodeName] = 1;
                }
                $result[$child->nodeName][] = xml_to_array($child);
            }
        }
    }

    return $result;
}

Test;

$s = '
        
            
                
                    
                    
                    
                    
                
            
        ';

$xml = new DOMDocument();
$xml->loadXML($s);
$xmlArray = xml_to_array($xml);
print_r($xmlArray);
// print_r($xmlArray['response']['resData']['contact:infData']['contact:status'][0]['@attributes']['s']);
// foreach ($xmlArray['response']['resData']['contact:infData']['contact:status'] as $status) {
    // echo $status['@attributes']['s'] ."\n";
// }
