动态创建XML从PHP到Actionscript 3

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();

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>

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.

}

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？

预先感谢您的任何帮助.

问候,

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

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？
