//打开

procedure TForm1.FormCreate(Sender: TObject);

  {必须用万一提供的 xml 测试文件, 才能有相同的返回值}

end;





//获取节点名称

procedure TForm1.Button1Click(Sender: TObject);

  node := node.ChildNodes[0]; {XMLDocument1.DocumentElement.ChildNodes[0].ChildNodes[0]}

  ShowMessage(node.NodeName); {姓名}

end;





//获取属性名称

procedure TForm1.Button2Click(Sender: TObject);

var

  node: IXMLNode;

begin

  node := XMLDocument1.DocumentElement;

  ShowMessage(node.AttributeNodes[0].NodeName); {备注}



  node := node.ChildNodes[0]; {XMLDocument1.DocumentElement.ChildNodes[0]}
