Flex读取xml文件

文章分类:Web前端

主要有两个方法：

（1）通过HTTPService

（2）通过URLLoader

代码如下：

mxml代码

import mx.rpc.http.HTTPService;

public const xmlUrl:String = "config.xml";

[Bindable] private var colors1:ArrayCollection;

[Bindable] private var colors2:XML;

private function init():void{

//方法一：通过HTTPService

var service:HTTPService = new HTTPService();

service.url = xmlUrl;

service.addEventListener(ResultEvent.RESULT, resultHandler);

service.send();

//方法二：通过URLLoader

var request:URLRequest = new URLRequest(xmlUrl);

var loader:URLLoader = new URLLoader(request);

loader.addEventListener(Event.COMPLETE, loaderCompleteHandler);

}

private function resultHandler(event:ResultEvent):void{

colors1 = event.result.colors.color;

}

private function loaderCompleteHandler(event:Event):void{

colors2 = new XML(event.target.data);

}
