Load XML file from addon domain without cross-domain Policy file

Question

Hello.
Assuming that there are two addon domains on the same server: /public_html/domain1.com       and      /public_html/domain2.com
I try to load XML file from domain2.com into domain1.com without using cross-domain policy file (since it doesn’t work on xml files in my case).
So the idea is to use php file in order to load XML and read it back to flash.
I’ve found an interesting scripts that seems to do the job but unfortunately I can't get it to work. In my opinion there is somewhere problem with AS3 part. Please take a look.
Here are the AS3/PHP scripts:
AS3 (.swf in www.domain1.com):
// location of the xml that you would like to load, full http address
var xmlLoc:String = "http://www.domain2.com/MyFile.xml";
// location of the php xml grabber file, in relation to the .swf
var phpLoc:String = "loadXML.php";
var xml:XML;
var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest(phpLoc+"?location="+escape(xmlLoc) );
loader.addEventListener(Event.COMPLETE, onXMLLoaded);
loader.addEventListener(IOErrorEvent.IO_ERROR, onIOErrorHandler);
loader.load(request);
function onIOErrorHandler(e:IOErrorEvent):void {
    trace("There was an error with the xml file "+e);
function onXMLLoaded(e:Event):void {
    trace("the rss feed has been loaded");
    xml = new XML(loader.data);
    // set to string, since it is passed back from php as an object
    xml = XML(xml.toString());
    xml_txt.text = xml;
PHP (loadXML.php in www.domain1.com):
<?php
header("Content-type: text/xml");
$location = "";
if(isset($_GET["location"])) {
    $location = $_GET["location"];
    $location = urldecode($location);
$xml_string = getData($location);
// pass the url encoded vars back to Flash
echo $xml_string;
//cURLs a URL and returns it
function getData($query) {
    // create curl resource
    $ch = curl_init();
    // cURL url
    curl_setopt($ch, CURLOPT_URL, $query);
    //Set some necessary params for using CURL
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   //Execute the curl function, and decode the returned JSON data
    $result = curl_exec($ch);
    return $result;
    // close curl resource to free up system resources
    curl_close($ch);
?>

I think you might be right about permissions/settings on the server for php. Unfortunately I'm not allowed to adjust them.
So I wrote my own script - this time I used file path instead of http address of the XML file.  It works fine in my case.
Here it is:
XML file on domain2.com:
<?xml version="1.0" encoding="UTF-8"?>
<gallery>
    <image imagePath="galleries/gallery_1/images/1.jpg" thumbPath="galleries/gallery_1/thumbs/1.jpg" file_name= "1"> </image>
    <image imagePath="galleries/gallery_1/images/2.jpg" thumbPath="galleries/gallery_1/thumbs/2.jpg" file_name= "2"> </image>
    <image imagePath="galleries/gallery_1/images/3.jpg" thumbPath="galleries/gallery_1/thumbs/3.jpg" file_name= "3"> </image>
</gallery>
swf  on domain1.com:
var imagesXML:XML;
var variables:URLVariables = new URLVariables();
var varURL:URLRequest = new URLRequest("MyPHPfile.php");
varURL.method = URLRequestMethod.POST;
varURL.data = variables;
var MyLoader:URLLoader = new URLLoader;
MyLoader.dataFormat =URLLoaderDataFormat.VARIABLES;
MyLoader.addEventListener(Event.COMPLETE, XMLDone);
MyLoader.load(varURL);
function XMLDone(event:Event):void {
    var imported_XML:Object = event.target.data.imported_XML;
    imagesXML = new XML(imported_XML);
   MyTextfield_1.text = imagesXML;
   MyTextfield_2.text = imagesXML.image[0].attribute("thumbPath");  // sample reference to attribute "thumbPath" of the first element
php file on domain1.com:
<?php
$xml_file = simplexml_load_file('../../domain2.com/galleries/gallery_1/MyXMLfile.xml');  // directory to XML file on the same server
$imported_XML = $xml_file->asXML();
print "imported_XML=" . $imported_XML;
?>

PS: for those who read the above discussion: the first and the second script work but you must test which one is better in your situation. The first script will also work between two domains on different servers. No cross domain policy file needed.
