Question

我正在尝试读取XML文件并在简单的列表组件或控制台中显示其内容。问题是事件监听器是在无限循环中触发的。

代码：

var myXML:XML;
var myLoader:URLLoader = new URLLoader();

myLoader.addEventListener(Event.COMPLETE, processXML);

myLoader.load(new URLRequest("/songs/songs.xml"));

function processXML(e:Event):void {
    myXML = new XML(e.target.data);
    trace(myXML.*);
}

xml文件：

<?xml version="1.0" encoding="utf-8"?>
<Songs>
    <Song>Sleep Away.mp3</Song>
    <Song>Kalimba.mp3</Song>
</Songs>

输出： <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> <Song>Kalimba.mp3</Song> <Song>Sleep Away.mp3</Song> ....

Answer 1

首先，这只是在IDE的时间轴上吗？如果是，您是否需要添加stop()？

其次，您可以在COMPLETE事件发布后立即从加载程序中删除侦听器。

function processXML(e:Event):void {
    myLoader.removeEventListener(Event.COMPLETE, processXML);
    myXML = new XML(e.target.data);
    trace(myXML.*);
}
