XMLWriter 有以下几个方法:

• BeginNode (Name)
• EndNode ()
• Attrib (Name, Value)
• WriteString (Value)
• Node (Name, Value)
• Close ()
• ToString ()

BeginNode 输出一个标签：

XML.BeginNode(“Foo”);

XML.BeginNode(“Foo”);
XML.Attrib(“Bar”, “Some Value”);

WriteString 方法：

XML.Node(“MyNode”, “My Value”);
//Produces: <MyNode>My Value</MyNode>

XML.BeginNode(“Foo”);
XML.WriteString(“Hello World”);
XML.EndNode();
//Produces <Foo>Hello
