PHP 从 XML 响应中获取属性

当我调用soap api 时，我得到这个响应

我想从这个文档获取状态属性， 我用这个代码

$xmlDomElement = new SimpleXMLElement(parent::__getLastResponse());

  $xmlDomElement->registerXPathNamespace("wss", "http://www.adonix.com/WSS");
    /** @var SimpleXMLElement $status */
    $status = $xmlDomElement->xpath("//multiRef[1]//status/text()");

    if ((int) $status[0]->__toString() == 0)
    {
    // my code
    }

但我收到错误

Undefined index: 0

回复有效吗？在这种情况下我怎样才能获得状态属性，它是 1

Answer 1

尝试：

$xmlDomElement = new SimpleXMLElement(parent::__getLastResponse());

$xmlDomElement->registerXPathNamespace("wss", "http://www.adonix.com/WSS");
$status = $xmlDomElement->xpath("//wss:saveResponse//saveReturn//status/text()");

if (isset($status[0]) && (int) $status[0]->__toString() == 0) {
    // my code
}
