次の関数を使用して、応答を返し、処理しています

public function getXML2($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    $response = curl_exec($ch);

    $xml = simplexml_load_string($response, NULL, NULL, "http://mws.amazonservices.com/schema/Products/2011-10-01");
    $xml->registerXPathNamespace('ns2', 'http://mws.amazonservices.com/schema/Products/2011-10-01/default.xsd');
    return $xml;

}

データをループしようとすると、何も返すことができません

foreach($xml->xpath('//ns2:ItemAttributes') as $event) {
    $event->registerXPathNamespace('ns2', 'http://mws.amazonservices.com/schema/Products/2011-10-01/default.xsd');
    echo var_export($event->xpath('//ns2:author'));
}

私は何を間違っていますか？

試しましたDOMDocumentか？

$dom = new DOMDocument;
$dom->loadXML($xml);

$xpath = new DOMXPath($dom);
$xpath->registerNamespace('ns2', 'http://mws.amazonservices.com/schema/Products/2011-10-01/default.xsd');

$el = $xpath->query('//ns2:ItemAttributes/ns2:Author');
var_dump($el->item(0)->nodeValue);

//string(14) "Slimming World"
