如何使用PHP解析来自PayPal API的SOAP响应？

Question

我试图解析为PHP PayPal的整合SOAP响应，我已经通过下面的帖子阅读：

parse an XML with SimpleXML which has multiple namespaces

这给伟大的见解，但我仍然无法弄清楚如何做正确的。这个SOAP事情非常复杂！

这里是SOAP响应我需要解析：

<?xml version="1.0" encoding="UTF-8"?>

这里是PHP代码中，我一直在努力，到目前为止，但没有结果：

$xml = simplexml_load_string($res, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/"); 
$xml->registerXPathNamespace('soap-env', 'http://schemas.xmlsoap.org/soap/envelope/'); 
$xml->registerXPathNamespace('xsi', 'http://www.w3.org/1999/XMLSchema-instance'); 
$xml->registerXPathNamespace('wsse', 'http://schemas.xmlsoap.org/ws/2002/12/secext'); 

foreach($xml->xpath('//getexpresscheckoutdetailsresponse') as $header) 
{ 
    var_export($header->xpath('//timestamp')); // Should output 'something'. 
} 

其中$水库包括完整的SOAP响应。我究竟做错了什么？任何帮助真的很感激！

预先感谢您。

一切顺利，

Fab。

您应该考虑使用像Zend_Soap_Client这样的库 - 它将为您处理SOAP-XML - 而不是您希望的每个响应的自定义xml格式。
