在flex中将子节点添加到XML

var xml:XML = <root></root>;
var child:XML =<child>Child Node</child>;
xml.appendChild(child);

var xml:XML = <root><child1>Child 1</child1></root>;
var child2:XML =<child2>Child 2</child2>;
xml.insertChildAfter(child1, child2);

var xml:XML = <root></root>;
var children:XMLList =<children<child1>Child 1</child1<child2>Child 2</child2></children>;
xml.appendChild(children);

var xml:XML = <root><child1>Child 1</child1></root>;
var children:XMLList =<children<child2>Child 2</child2<child3>Child 3</child3></children>;
xml.insertChildAfter(child1, children);
