这些delphi 代码怎么转给 BCB

  我对delphi不大熟悉， 但网络上delphi的代码多，BCB的少，想照着delphi的代码改称BCB的，但遇到一些额问题不知怎么转为ＢＣＢ。　下面是摘录一些简短的。

(1)
type
  IXMLDOMImplementation = interface;
  IXMLDOMImplementationDisp = dispinterface;


(2)
IXMLDOMNamedNodeMapDisp = dispinterface
    ['{2933BF83-7B36-11D2-B20E-00C04F983E60}']
    function  removeNamedItem(const name: WideString): IXMLDOMNode; dispid 85;
    property item[index: Integer]: IXMLDOMNode readonly dispid 0; default;
    property Value:Integer WriteOnly Write fValue Stored True  nodefault;     
  property MyImplClass: TMyImplClass read FMyImplClass implements IMyInterface;  //其中 typeIMyInterface = interface               
  end;

(3)
  IXMLDOMNode = interface(IDispatch)
    ['{2933BF80-7B36-11D2-B20E-00C04F983E60}']
  //....
  end;
  IID_IXMLDOMImplementation: TGUID = '{2933BF8F-7B36-11D2-B20E-00C04F983E60}';
