Question

这是我的整个剧本，因为我似乎无法弄清楚问题出在哪里。

症状是我添加孩子（书）的地方，也不是用拇指正确和顺序添加的适当位置。结果，令我惊讶的是，到目前为止，我能让这些出现的唯一方法是编写一个错误的跟踪语句，它会以某种方式在左上角弹出它们。任何建议将不胜感激！谢谢!!

Answer 1

在我看来，您并没有正确加载XML。您应该使用URLLoader，而不是加载XML来加载XML。然后，您需要等到触发Event.COMPLETE来解析数据并添加文本字段。

来自sephiroth（http://www.sephiroth.it/tutorials/flashPHP/E4X/）：

import flash.net.URLLoader
import flash.net.URLRequest
import flash.xml.XML
import flash.event.*
import flash.error.*

var mainXML:XML;
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onComplete);
loader.load(new URLRequest("http://www.sephiroth.it/tutorials/flashPHP/E4X/files/test.xml"));


function onComplete(evt:Event)
{
    mainXML = new XML(loader.data)
    trace("xml loaded, start parsing using E4X syntax");
}

好吧，既然你已经大量编辑了你的问题，是的，很明显你已经拥有了那个问题。在尝试将其解析为xml对象之前，我会尝试跟踪/观察loader.data，以确切了解您尝试将哪些数据解析为XML。听起来你可能得到了一些你并不期望的数据。

我的代码最多只显示XML List中的一个结果的原因是因为我在循环之外实例化一个TextField，它从XML的许多节点中绘制var i。要正确显示每个节点的文本字段，我需要为每个var i实例化TextField。像这样：

function callThumbsW():void {
for (var i:Number = 0; i < my_totalW; i++) {

    var thumb_urlW = my_imagesW[i].thumb;
    var book = my_imagesW[i].TITLE;

    var textHolder:TextField = new TextField;
    container_mcW.addChild(textHolder);

这导致了即时的满足感。

使用AS3解析XML
