//打开
procedure TForm1.FormCreate(Sender: TObject);
begin
  XMLDocument1.LoadFromFile('c:\temp\test.xml');
  {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);
var
  node: IXMLNode;
begin
  node := XMLDocument1.DocumentElement;
  ShowMessage(node.NodeName); {科室名单}

  node := node.ChildNodes[0]; {XMLDocument1.DocumentElement.ChildNodes[0]}
  ShowMessage(node.NodeName); {人员}

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