使用PHP读取SOAP响应

Question

我正在尝试用PHP读取SOAP响应，但是我收到了这个错误：

Warning: simplexml_load_string(): Entity: line 1: parser error : Extra content at the end of the document in C:\xampp\htdocs\clinics\sedeeq.php on line 10

Warning: simplexml_load_string(): :complexType></xs:element></xs:choice></xs:complexType></xs:element></xs:schema> in C:\xampp\htdocs\clinics\sedeeq.php on line 10

Warning: simplexml_load_string(): ^ in C:\xampp\htdocs\clinics\sedeeq.php on line 10

这是我的PHP代码：

$soap_client = new SoapClient("http://test.com/WebSrvOutApp/OutApp.asmx?WSDL");
        $data = $soap_client->OutGetOpdSchedule("test","test_2020");
$xml = simplexml_load_string($data->OutGetOpdScheduleResult->any);
