I am using the following code for finding the child nodes from the above XML.
我使用以下代码从上面的XML中查找子节点。
private function loadXML(targetURL:String):void
{
urlLdr.load(new URLRequest(targetURL));
urlLdr.addEventListener(Event.COMPLETE,urlLdr_complete);
}
private function urlLdr_complete(event:Event):void
{
var xmlData:XML=new XML(URLLoader(event.currentTarget).data);
for each (var t:XML in xmlData.children())
{
Alet.show(t.Name());
}
}}
But I only 2 Children nodes(TabNavigator and NavigatorContent).How i get all the children Nodes? Can any one help me please???
但我只有2个子节点（TabNavigator和NavigatorContent）。我如何得到所有孩子的节点？有人可以帮我吗???
My code is given below. I got only child nodes now.. haven't got the parent node.please help me for getting the parent and child nodes..
我的代码如下。我现在只有子节点..没有父节点。请帮助我获取父节点和子节点..

The children() method of class XML only returns the direct children of the current object. If you want to go through the whole document you need to recursively call your method on each children.
类XML的children（）方法只返回当前对象的直接子节点。如果您想浏览整个文档，则需要以递归方式为每个孩子调用您的方法。
So you need to write something like:
所以你需要写一些像：
private function handleOneNode(node:XML):void {
var children:XMLList = node.children();
if ( children.length() == 0 ) {
//Handle Leaf node -> Create ui object, or whatever
} else {
//Non terminal node, check children
for each (var child:XML in children ) {
handleOneNode(child);
}
}
}
And in your handler you call it:
在你的处理程序中，你称之为：
var xmlData:XML=new XML(URLLoader(event.currentTarget).data);
handleOneNode(xmlData)
EDIT In order to access the parent node you simply have to add an additional parameter to the handleOneNode function.
编辑为了访问父节点，您只需向handleOneNode函数添加一个附加参数。
private function handleOneNode(node:XML, parent:XML=null):void {
var children:XMLList = node.children();
if ( children.length() == 0 ) {
//Handle Leaf node -> Create ui object, or whatever
} else {
//Non terminal node, check children
for each (var child:XML in children ) {
handleOneNode(child, node);
