PHP curl soap - 获取变量

Question

我看过多篇关于这个主题的帖子，但似乎我尝试过的每个人都没有返回变量。我要做的就是返回 SessionIdentifier 和 SessionIdentifierHash。下面是我正在尝试的代码。

$soapresults = <<< LOL

LOL;
$soap = simplexml_load_string($soapresults);
$soap->registerXPathNamespace('ns1', 'http://schemas.sendwordnow.com/ws/2010/05/PublicSessionManager');
$test = (string) $soap->xpath('//ns1:OperationResult/ns1:IsSuccess');
var_dump($test);

Answer 1

我还发现这也有效，所以不确定这是否是更好的方法。

$soap_response = $soapresults;
$dom_result = new DOMDocument;
if (!$dom_result->loadXML($soap_response))
    throw new Exception(_('Error parsing response'), 11);
    $my_val = $dom_result->getElementsByTagName('SessionIdentifier')->item(0)->nodeValue;
var_dump($my_val);

Answer 2

问题在于响应中有更多的命名空间元素。因此，您需要在整个迭代过程中继续使用registerXPathNamespace()。不过，可能有更好的方法：

$soap = simplexml_load_string($soapresults);
$soap->registerXPathNamespace('ns1', 'http://schemas.sendwordnow.com/ws/2010/05/PublicSessionManager');
$test = $soap->xpath('//ns1:OperationResult');
foreach ($test as $el) {
    $el->registerXPathNamespace('ns2', 'http://schemas.datacontract.org/2004/07/SWN.Notification.PublicSessionManagement.Contracts.DataContracts');
    $el2 = $el->xpath("//ns2:SessionToken");
    foreach ($el2 as $val) {
        $val->registerXPathNamespace('ns3', 'http://schemas.datacontract.org/2004/07/SWN.Framework.SessionState');
        $sessionIdentifier = $val->xPath("//ns3:SessionIdentifier")[0];
        $sessionIdentifierHash = $val->xPath("//ns3:SessionIdentifierHash")[0];
    }
}
echo "Identifier: ".$sessionIdentifier." - Hash: ". $sessionIdentifierHash;

结果：

标识符：265277237 - 哈希 2dSXW81GQxNy1iYzRlLTRjZjItYjYyNS01MmEyZDM5M2RlMjI=

请注意，SessionIdentifierHash 周围有一些空格。不知道是不是这个回复的本意。
