How to display a simple rss feed?

Question

Hi,
I've build a simple application that has a httpservice called rss that calls "http://www.nytimes.com/services/xml/rss/nyt/GlobalBusiness.xml" and retrieves the rss feed. Under test operation I can see it returning the feed.
When the init() function is called the httpservice is called and passed to a datagrid.
However, when I run it I get the following fault.
Security error accessing url
Destination: DefaultHTTP
In the console I get the following messeage:
Warning: Domain www.nytimes.com does not specify a meta-policy.  Applying default meta-policy 'master-only'.  This configuration is deprecated.  See http://www.adobe.com/go/strict_policy_files to fix this problem.
Error: Request for resource at http://www.nytimes.com/services/xml/rss/nyt/GlobalBusiness.xml by requestor from http://localhost:8888/Newsroom-debug/Newsroom.swf/[[DYNAMIC]]/4 is denied due to lack of policy file permissions.
*** Security Sandbox Violation ***
Connection to http://www.nytimes.com/services/xml/rss/nyt/GlobalBusiness.xml halted - not permitted from http://localhost:8888/Newsroom-debug/Newsroom.swf
[Unload SWF] /Newsroom-debug/Newsroom.swf
I have checked different posts online and in this forum describing crossdomain.xml and settings in the flash player global settings to resolve this issue, but I can for some reason not get it to work.
I want to be able to take rss feeds from any site and display them in a simple datagrid?
Any suggestions?
Below is the application code.
Br,

OK.
Tried out your suggestion and it works!
Thanks saisri2k2
1) I created an http service which calls a php file:
<mx:HTTPService
            id="rssNewYorkTimes"
            url="php/newyorktimes.php"
            result="rssNewYorkTimes_resultHandler(event)"
            resultFormat="e4x" />
2) The php file then gets the feed and passes it back to the rssNewYorkTimes_resultHandler:
<?php
  $feed = 'http://www.nytimes.com/services/xml/rss/nyt/GlobalBusiness.xml';
  $rawfeed = @file_get_contents($feed);
  print $rawfeed; 
?>
3) the resulthandler then processes the feed and puts it in an arraycollection that can be passed to the datagrid:
protected function rssNewYorkTimes_resultHandler(event:ResultEvent):void
                var xmlList:XMLList = event.result.channel.item as XMLList;
                for each(var item:XML in xmlList)
                    rssCollection.addItem({title: item.title, description:item.description, source:item.link});
                buildRss();
Thanks also to Chris Black for his post which explains in detail how this trick is done!
