黄聪：Delphi 中的 XMLDocument 类详解，8 - 添加与删除节点

unit Unit1;

interface

uses

Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

Dialogs, xmldom, XMLIntf, msxmldom, XMLDoc, StdCtrls;

type

TForm1 = class(TForm)

XMLDocument1: TXMLDocument;

Memo1: TMemo;

Button1: TButton;

Button2: TButton;

procedure FormCreate(Sender: TObject);

procedure Button1Click(Sender: TObject);

procedure Button2Click(Sender: TObject);

private

{ Private declarations }

public

{ Public declarations }

end;

var

Form1: TForm1;

implementation

{$R *.dfm}

//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;

//添加

procedure TForm1.Button1Click(Sender: TObject);

var

newNode, newNodeAdd: IXMLNode;

begin

newNode := XMLDocument1.DocumentElement.AddChild('人员');

newNode.Attributes['职务'] := '秘书';

newNodeAdd := newNode.AddChild('姓名');

newNodeAdd.Text := '小翠';

newNodeAdd := newNode.AddChild('性别');

newNodeAdd.Text := '女';

Memo1.Lines := XMLDocument1.XML; {查看}

{会在尾部增加:

<人员 职务="秘书"><姓名>小翠</姓名><性别>女</性别></人员>

}

end;

//删除

procedure TForm1.Button2Click(Sender: TObject);

var

nodeList: IXMLNodeList;

begin

nodeList := XMLDocument1.DocumentElement.ChildNodes;

nodeList.Delete(nodeList.Count-1); {删除最后一条}

Memo1.Lines := XMLDocument1.XML; {查看}

end;

end.
