我敢打赌，问题是当您有一个封装在 XML 数据包中的 SOAP 数据时，您可以使用 PHP 中的哪个函数来提取 SOAP 数据？

我刚刚研究了一个小时，因为我遇到了类似的问题。归根结底是，仅仅因为 SOAP 包装在 XML 中并不意味着您可以使用“简单”;-) XML 函数来提取所需的 SOAP 信息。

您必须牢记名称空间。就我而言，我有这样的情况：

<?xml version="1.0" encoding="utf-8"?>
 * <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
 * <soap:Body><Request_MerchantStatementResponse xmlns="http://www.netcash.co.za/netserv/ncUpload">
 * <Request_MerchantStatementResult>2010/11/06 00:00:00\tOBL\t0\t\tOpening Balance\t100000.00\t+\t0.00\t\t\t\t\t\t\t\r</Request_MerchantStatementResult>
 * </Request_MerchantStatementResponse></soap:Body>
 * </soap:Envelope>

我需要提取“Request_MerchantStatementResult”，仅此而已。解决方案是指定我的返回 XML 中引用的名称空间。

    $xml = simplexml_load_string($response);

    echo $xml->children('http://schemas.xmlsoap.org/soap/envelope/')
->children('http://www.netcash.co.za/netserv/ncUpload')
->Request_MerchantStatementResponse
->Request_MerchantStatementResult;

如果您只是 print_r simplexml_load_string 的结果，那么问题就出现了，您什么也得不到。因此请务必指定您的名称空间。

我离题了，而不是

echo $xml->children('http://schemas.xmlsoap.org/soap/envelope/')
    ->children('http://www.netcash.co.za/netserv/ncUpload')
    ->Request_MerchantStatementResponse
    ->Request_MerchantStatementResult;

我应该有：

$result = $xml->children('http://schemas.xmlsoap.org/soap/envelope/')
    ->children('http://www.netcash.co.za/netserv/ncUpload')
    ->Request_MerchantStatementResponse;

echo $result->Request_MerchantStatementResult;
