делай так:

myDoc = new XML();
myDoc.load ("123.xml");
function showNodes (node){
trace(node)
trace (node.nodeName + ": " + node.nodeValue);
for (var child = node.сhildNodes.length; child; child--) {
showNodes(node.сhildNodes[child]);
trace(node.сhildNodes[child])
}
}
myDoc.onLoad = function(){
showNodes (this.firstChild);
}
