动态创建XML从PHP到Actionscript 3

I am trying to dynamically create an XML file using php like this:

我试图使用PHP动态创建一个XML文件,如下所示:

  header ("content-type: text/xml");

  // create doctype
  $dom = new DOMDocument("1.0");

  // create root element
  $root = $dom->createElement("tracklist");
  $dom->appendChild($root);
  $dom->formatOutput=true;

  // create child element
  foreach ($commonPlaylist as $value) {

     $trackArray = getTrackForID($value['ID']);

     $item = $dom->createElement("track");
     $root->appendChild($item);

     foreach ( $trackArray as $key => $value) {
      $attr = $dom->createAttribute($key);
      $item->appendChild($attr);

          $attrValue = $dom->createTextNode($value);
      $attr->appendChild($attrValue);
     }

  }

 echo $dom->saveXML();

The output of the file is normal working xml

该文件的输出是正常工作的xml

<?xml version="1.0"?>
   <tracklist>
        <track ID="4" title="Track01" artist="Artist01" url="" length="" coverURL=""/>
        <track ID="1" title="Track02" artist="Artist02" url="" length="" coverURL=""/>
        <track ID="8" title="Track03" artist="Artist03" url="" length="" coverURL=""/>
   </tracklist>

However if I want to get this data into as3 with the following code:

但是,如果我想使用以下代码将此数据转换为as3:

var myLoader:URLLoader = new URLLoader();
myLoader.load(new URLRequest("getPlaylist.php"));
myLoader.addEventListener(Event.COMPLETE, processXML);

function processXML(e:Event):void
{
    var myXml:XML= new XML(e.target.data);
    trace(myXml);  // The variable is being traced.

}

I don't get any output at all. If I read the file as a String I get the whole PHP code. What am I doing wrong?

我根本没有得到任何输出。如果我将该文件作为String读取,我将获得整个PHP代码。我究竟做错了什么?

Thank you in advance for any help.

预先感谢您的任何帮助。

3 个解决方案

#1

If I read the file as a String I get the whole PHP code

如果我将该文件作为String读取,我将获得整个PHP代码

It sounds like it's not being executed server-side. Are you hosting it on a server with PHP installed?

听起来它不是在服务器端执行。您是否在安装了PHP的服务器上托管它?

#2

Check the variable name

检查变量名称

You're tracing myXML & the XML variable name is myXml

您正在跟踪myXML,XML变量名称是myXml

#3

Is processXML() actually triggered? Try modifying it like in the following code and see if you get the "Hi!" part traced.

processXML()实际上是否被触发了?尝试修改它,如下面的代码,看看你是否得到“嗨!”部分追踪。

function processXML(e:Event):void
{
    trace('Hi!');
    var myXml:XML= new XML(e.target.data);
    trace(myXML);
}

BTW, using a Flash debugger might be much more useful from trying to guess what went wrong :) Since the one shipped with Flash Professional sucks big time I can only recommend DeMonster debugger which saved me a lot of time while working on Flash projects. It also wouldn't hurt to have an HTTP traffic analysis tool like Fiddler.

顺便说一下,使用Flash调试器可能会更有用,因为我猜测出错了:)由于Flash Professional附带的那个很糟糕,我只能推荐DeMonster调试器,这使我在处理Flash项目时节省了大量时间。拥有像Fiddler这样的HTTP流量分析工具也没有什么坏处。
