继续研究NativeXML: NativeXml的方法属性:ANativeXml := TNativeXml.Create(Self);//创建 ANativeXml.XmlFormat := xfReadable; //格式 ANativeXml.EncodingString := 'UTF-8';//编码 ANativeXml.ExternalEncoding := seUTF8; ANativeXml.LoadFromFile();//从文件夹中导入XML文件 ANativeXml.SaveToFile();//XML文件保存到文件夹 节点的方法属性: ANativeXml.Root;//XML文件的根节点,注意一切都从根开始 ANativeXml.Root.NodeByName(‘节点名’);//通过节点名获得节点 NativeXml.Root.Attributes;//节点的属性对象 NativeXml.Root.ChildContainers;//节点的子节点对象 NativeXml.Root.NodeNew();//增加新的子节点 NativeXml.Root.Name;//节点名 NativeXml.Root.Value;//节点值 七、添加节点 根节点的添加,可以在创建时直接指定根节点: var XmlDoc: TnativeXml; Node:TxmlNode; Begin XmlDoc := TNativeXml.CreateName('Data'); //创建根节点的语法 XmlDoc.XmlFormat := xfReadable; ... ... 添加节点有以下几种方法: Node:=xmlDoc.Root.NodeNew(‘BasicDataNo’); Node.value:=’1’; XmlDoc.Root.NodeNew(‘name’).value:=’sam’; xmlDoc.Root.WriteString(‘sex’,’male); ____________________________________ 更加完整的参考万一的博客,在这里引用一下:
