在PHP中读取SOAP响应

我在阅读SOAP响应时遇到问题，有人能帮我看看吗

这是我正在使用的代码

<?php 
//Data, connection, auth
$dataFromTheForm = $_POST['fieldName']; // request data from the form
$soapUrl = "https://cig.dhl.de/services/sandbox/soap"; // asmx URL of WSDL

$soapPassword = "password"; // password

//variables
//account details

您可以使用XPath：

/soap:Envelope/soap:Body/bcs:CreateShipmenterResponse/CreationState/LabelData/cis:shipmentNumber

我使用测试工具测试了XPath

有关XPath示例，请参见以下答案：

由于名称空间不同，使用XPath时需要注册它使用的名称空间。下面的代码使用XPath获取shipmentNumber，但直接访问labelUrl，因为它不在另一个命名空间中

$xml=simplexml_load_string($response2);
$xml->registerXPathNamespace("cis", "http://dhl.de/webservice/cisbase");

$labelData = $xml->xpath("//LabelData")[0];
echo "shipmentNumber=".$labelData->xpath("descendant::cis:shipmentNumber")[0].PHP_EOL;
echo "labelUrl=".$labelData->labelUrl.PHP_EOL;

如果您在
echo
以外的任何地方使用这些值，您可能需要将它们转换为字符串-
（string）$labelData->labelUrl
OP，为什么不使用
new SoapClient（）
？，无论如何，请尝试
$parser->shipmentNumber如果这解决了您的问题，您可以将其标记为已回答（答案左侧的勾号）谢谢。
$xml=simplexml_load_string($response2);
$xml->registerXPathNamespace("cis", "http://dhl.de/webservice/cisbase");

$labelData = $xml->xpath("//LabelData")[0];
echo "shipmentNumber=".$labelData->xpath("descendant::cis:shipmentNumber")[0].PHP_EOL;
echo "labelUrl=".$labelData->labelUrl.PHP_EOL;
