SOAP Message wie ein XML auslesen?

[samso]

Wo genau ist das Problem? Mein gerade hingeschmiertes Testprogram funktioniert:

Delphi-Quellcode:

uses
  Xml.XMLIntf, Xml.XMLDoc;

const
  SoapMessage = '<?xml version="1.0"?>' +
  '<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" ' +
  'xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">' +
  '<SOAP-ENV:Body><KeyNewRequest xmlns="http://tempuri.org/">' +
  '<KeyNewRequest><GUID>EF629EB757764FBC9EA41E0611093B32</GUID>' +
  '<RequestNumber>BEST1001</RequestNumber><KeyOwner>AB100</KeyOwner>' +
  '</KeyNewRequest></KeyNewRequest></SOAP-ENV:Body></SOAP-ENV:Envelope>';

procedure TForm1.Button1Click(Sender: TObject);
var
  SoapDoc: IXMLDocument;
  Node: IXMLNode;
  NodeList: IXMLNodeList;
  a: String;
begin
  Memo1.Clear;
  SoapDoc := LoadXMLData(SoapMessage);
  Node := SoapDoc.DocumentElement;
  if Node<>nil
  then begin
    NodeList := Node.ChildNodes;
    if (NodeList<>nil) and (NodeList.Count=1)
    then begin
      Node := NodeList[0];
      NodeList := Node.ChildNodes;
      if (NodeList<>nil) and (NodeList.Count=1)
      then begin
        Node := NodeList[0];
        a := Node.Attributes['xmlns'];
        Memo1.Lines.Add(Node.LocalName + '=' + a);
        NodeList := Node.ChildNodes;
        if (NodeList<>nil) and (NodeList.Count=1)
        then begin
          NodeList := NodeList[0].ChildNodes;
          Node := NodeList.FindNode('RequestNumber');
          if Node<>nil
          then
            Memo1.Lines.Add(Node.LocalName + '=' + Node.Text);
        end;
      end;
    end;
  end;
end;
