내가 뭘

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')); 
} 

아무것도에게 반환 할 수없는 나는 내가 돌아갑니다 다음 함수를 사용하고 내가 데이터를 통해 루프를 시도 할 때 과정은

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; 

} 

을 repsonses 잘못된?

Answer 1

DOMDocument을 사용해 보셨습니까?

$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"
