我搜索连接到Web服务，但是当我调用该方法时，我获得了此错误“Element”OutputObj“不包含单个文本节点”。
这是我创建导入我的WSDL文件的单位：

这是调用Web服务方法的代码：
Procedure PrcSendSOAPRequest(const ServiceID:string; InputObj: Variant; PmPathXML: string);

D6 : richiesta di Rigetto (IE819)
InputObj
se ServiceID D2 : Protocollo di cui si vuole conoscere l'esito
}
var

SOAP_RequestMsg : MessageDTO;
SOAP_ResponseMsg : MessageDTO;
XMLDto_Element : XmlDTO;
XMLDtoArray : ArrayOfXmlDTO;
begin
FMEXPTXTEAD := TFMEXPTXTEAD.Create(Application);
try
with FMEXPTXTEAD do
begin
// richiesta di Invio Draft IE815
if ServiceID = D1 then
begin
XMLDto_Element := XmlDTO.Create;
SOAP_RequestMsg := MessageDTO.Create;
SOAP_ResponseMsg := MessageDTO.Create;
try
XMLDto_Element.xml := StringToByteArray(PmPathXML);
SetLength(XMLDtoArray, 1);
XMLDtoArray[0] := XMLDto_Element;
// MESSAGGIO DI RICHIESTA
SOAP_RequestMsg.serviceID := ServiceID;
SOAP_RequestMsg.xmlList := XMLDtoArray;
// MESSAGGIO DI RISPOSTA
SOAP_ResponseMsg := GetDispatcherBean(False,'',HTTPRIO1,0).dispatcher(SOAP_RequestMsg);
// LETTURA DEL MESSAGGIO DI RISPOSTA
PrcReadSOAPResponse(D1,SOAP_ResponseMsg);
finally
begin
XMLDto_Element.Free;
SOAP_RequestMsg.Destroy;
SOAP_ResponseMsg.Destroy;
end;
end;
end;
end;
finally
FMEXPTXTEAD.Close;
end;
这是来自Web服务的XML响应：

<soapenv:Body>
<ns2:dispatcherResponse xmlns:ns2="http://dispatcher.domest.it.sogei">

</dispatcherReturn>
</ns2:dispatcherResponse>
</soapenv:Body>
</soapenv:Envelope>
当我调用GetDispatcherBean（False，''，HTTPRIO1,0）.dispatcher（SOAP_RequestMsg）时，我得到了错误。
在RIO的BeforeExecute上，我只是控制XML请求它就像使用SoapUI的XML请求一样。
在RIO的AfterExecute上，我只是控制XML响应就像使用SoapUI的XML响应一样。
GetDispatcherBean（False，''，HTTPRIO1,0）.dispatcher（SOAP_RequestMsg）返回一个MessageDTO，它是在UNDispatcherBean单元中定义的，但我认为Delphi没有正确解析对象MessageDTO的XML响应。
有关错误的任何想法？我必须在哪里寻找原因？
这是我的第一个使用Web Service和SOAP的项目，我希望不要写出这样的问题。
