关于Flex查询信息并显示的问题？那个高手帮忙解答下谢谢了.
这是配置文件的内容所有的信息都从这里取
- XML code

这是TitleWindows组建<?xml version="1.0" encoding="utf-8"?><mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="492" height="364" title="Command Reference" showCloseButton="true" close="PopUpManager.removePopUp(this);" color="#F1F8F9"> <mx:Script> <!--[CDATA[ private function init():void { var url:URLRequest = new URLRequest("command-info.xml"); var loader:URLLoader = new URLLoader(); loader.addEventListener(Event.COMPLETE,onComplete); loader.load(url); } private function onComplete(event:Event):void{ var result:URLLoader = URLLoader(event.target); datas = XML(result.data); } ]]--> </mx:Script> <mx:Script> <![CDATA[ import mx.collections.ICollectionView; import mx.events.ListEvent; /* * Point area through the contents of the drop-down menu start */ private function tree_itemClick(evt:ListEvent):void { //Define the point add Tree Event use come true contents of the drop-down menu start var item:Object = Tree(evt.currentTarget).selectedItem; //According the condition judge the point content if (treeXML.dataDescriptor.isBranch(item)) { treeXML.expandItem(item, !treeXML.isItemOpen(item), true); } } /* * Request the node of number */ private function tree_labelFunc(item:XML):String { var children:ICollectionView; var suffix:String = ""; if (treeXML.dataDescriptor.isBranch(item)) { children = treeXML.dataDescriptor.getChildren(item); suffix = " (" + children.length + ")"; } return item[treeXML.labelField] + suffix; } ]]> </mx:Script> <mx:Script> <![CDATA[ /* * Default show all node of contents */ private function initApp():void { for each(var item:XML in this.treeXML.dataProvider) this.treeXML.expandChildrenOf(item,true); } ]]> </mx:Script> <mx:Script> <![CDATA[ import mx.managers.PopUpManager; [Bindable] public var selectedNode:XML; // Event handler for the Tree control change event. public function treeChanged(event:Event):void { selectedNode=Tree(event.target).selectedItem as XML; } [Bindable] [Embed("images/skin/titlewindow/titleWindowBg.png")] public var VBoxBg:Class; [Bindable] [Embed("images/tree/icon/point.png")] public var point:Class; ]]> </mx:Script> <mx:XML id="dynamicTreeXML" source="assets/configfiles/commandTwo-info.xml"/> <mx:VBox x="30" y="10" height="284" width="432"> <mx:Tile width="429" height="23"> <mx:Label text="A B C D E F G H I Z K L M N O P Q R S T U X Y Z" width="418" height="23" fontWeight="bold" fontSize="13" fontFamily="Georgia" color="#3291C3"/> </mx:Tile> <mx:Label text="Select Command" width="104" height="23" fontSize="12" color="#3291C3" fontWeight="bold"/> <mx:HBox width="423" height="226"> <mx:Tree id="treeXML" change="treeChanged(event)" creationComplete="initApp()" dataProvider="{dynamicTreeXML}" labelField="@label" labelFunction="tree_labelFunc" itemClick="tree_itemClick(event)" rowCount="6" showRoot="false" width="200" height="224" backgroundColor="#E2F5FA" color="#3291C3"/> <mx:TextArea width="210" height="223" color="#3291C3" text="{selectedNode.@description}" /> </mx:HBox> </mx:VBox> </mx:TitleWindow>
我的问题是通过怎样的方式在点击 A B C D E F。。。。。。也就是定义的首字母时，在左边的Tree中显示XML定义的信息里相关字母开头的Command ？
A B C D 怎样定义才能是可点击的，本人新手很多都不懂，希望大家多多提意见 或者是用其他的方法实现这样的功能，多多指点。
[解决办法]
如(思路没做测试)：
- XML code
[Bindable]private var xmlValue:XMLListCollection;private function queryXML(par:String):void{ xmlValue = dynamicTreeXML.command.(contains(@label,par))} <mx:Tree id="treeXML" dataProvider="{xmlValue }" labelField="@label" />..
