我尝试了以下内容：

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

         </ipgapi:ipgapiorderresponse>
      </soap-env:body>
   </soap-env:header>
</soap-env:envelope>';

$xml = simplexml_load_string($responseXML);
print_r($xml);
// Returns empty object

我也尝试了以下内容：

$xml = new SimpleXMLElement($responseXML);
print_r($xml);
// This also returns empty object

有人可以帮我弄清楚这有什么问题吗？

Answer 1

将print_r();与SimpleXMLElement一起使用通常不会提供任何有用的信息。相反，您应该使用输出原始XML的asXML()。

$xml = simplexml_load_string($responseXML);
echo $xml->asXML();

哪个给出了

<?xml version="1.0" encoding="UTF-8"?>
<soap-env:envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
   <soap-env:header>
      <soap-env:body>
...

您可以使用类似......

之类的内容来访问数据

$xml = simplexml_load_string($responseXML);
$body = $xml->xpath("//soap-env:body");
$bodyData = $body[0]->children("ipgapi", true);
echo $bodyData->ipgapiorderresponse->approvalcode;

所以$bodyData是<ipgapi:ipgapiorderresponse ...>元素，因此访问其中的每一部分都是使用最后一行。您可以使用元素名称（减去名称空间前缀ipgapi，因为之前已通过children()调用处理此问题）。该行输出
