Dynamically generated XML from PHP to ActionScript 3

I am trying to dynamically create an XML file using php, for example:

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();

File output normal working 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 in as3 with the following code:

 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 anything at all. If I read the file as a String, I will get all the PHP code. What am I doing wrong?

Thanks in advance for any help.

It seems like it is not running on the server side. Do you host it on a server with PHP installed?

Check variable name

  • You are tracking myXML and the XML variable name is myXml

Does processXML() really work? Try changing it, as in the following code, and see if you get "Hello!". part is traceable.

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

BTW using a flash debugger can be much more useful to try to guess what went wrong :) Since one comes with Flash Professional it sucks a lot of time I can only recommend the DeMonster Debugger , which saved me a lot of time when working on Flash projects. It also does not hurt to have an HTTP traffic analysis tool, for example Fiddler .
