programming flash

I have a tree, nodes loaded from XML, now i want to search in tree like:http://www.shockwave-india.com/blog/?archive=2005_03_13_archive.xml.

code AS:


import mx.controls.Tree;
class TreeNavMenu extends MovieClip {
 var menuXML:XML;
 var menuTree:Tree;
 function TreeNavMenu() {
 // Set up the appearance of the tree and event handlers
 
  menuTree.setStyle("fontFamily", "_sans");
  menuTree.setStyle("fontSize", 12);  
  menuTree.setStyle("depthColors", [0x003366,0x013972,0x014383,0x01498F,0x01509C,0x0153A3])
  menuTree.setStyle("backgroundColor",0xFFFFFF)
  menuTree.setStyle("borderStyle", "none");
  menuTree.setStyle("color",0xFFFFFF);  
  //this.tree.setStyle("rollOverColor",0x333333);
  menuTree.setStyle("selectionColor", 0x666666);  
  menuTree.setStyle("textRollOverColor", 0x000000);
  menuTree.setStyle("textSelectedColor", 0x000000);
 
  // Load the menu XML
  var treeNavMenu = this;
  menuXML = new XML();
  menuXML.ignoreWhite = true;
  menuXML.load("TreeNavMenu.xml");
  menuXML.onLoad = function() {
   treeNavMenu.onMenuLoaded();
  };
 }
 function change(event:Object) {
  if (menuTree == event.target) {
   var node = menuTree.selectedItem;
   //trace(node)
   // If this is a branch, expand/collapse it
   if (menuTree.getIsBranch(node)) {    
    menuTree.setIsOpen(node, !menuTree.getIsOpen(node), true);
 
   }
   // If this is a hyperlink, jump to it
   var url = node.attributes.url;
   if (url) {
    getURL(url, "_top");
   }
   // Clear any selection
   menuTree.selectedNode = null;
  }
 }
 function onMenuLoaded() {
  menuTree.dataProvider = menuXML.firstChild;
  menuTree.hScrollPolicy = "on";
  menuTree.maxHPosition = 150;
  menuTree.addEventListener("change", this);
 }
}

This is my XML:


<?xml version="1.0" encoding="iso-8859-1"?>
<node label=" Ha Noi">
 <node label=" Attractions">
  <node label="Chua Mot Cot" />
  <node label="Lang Chu Tich" />
  <node label="Quoc Tu Giam" />  
 </node>
 <node label=" Where to stay">
  <node label=" Five Stars">
   <node label="Horizon Hotel" />
   <node label="Daewoo Hotel" />
  </node>
  <node label=" Four Stars">
   <node label="Eden Hotel" />  
  </node>
 </node> 
</node>
<node label=" Ho Chi Minh">
 <node label=" Attractions">
  <node label="Nha Tho Duc Ba"  />
  <node label="Dinh Doc Lap"  />
  <node label="Chua Xa Loi"  />
 </node>
 <node label=" Where to stay">
  <node label=" Five Stars">
   <node label="New World Hotel"  />
   <node label="Sheraton Hotel"  />
