Greasemonkey help with remote xml using jquery

[ertaboy356b]

Hi, I recently used greasemonkey (actually, it's just today). I have no experience about its API whatsoever. I have found a script that lets you use jquery for greasemonkey. I also found a script that let you use the gm_xmlhttprequest with the jquery wrapper ($.post, $.get).

Now I have a problem with greasemonkey requesting xml file from a remote host. I created a script data.xml which retrieves data from a server and returns it as an xml file. Greasemonkey can't seem to request this file from this server, probably because of security reasons. I've tried requesting it from localhost but failed.

Any workaround regarding this?? The script can be read below btw.

XHRs are subject to the Same Origin-policy.
Unless you enabled Cross-Origin Resource Sharing on the remote host, it's only natural you're not receiving any data.

Is it possible to use localhost with it? I don't know how to make XHR work in GreaseMonkey.. I've seen people done it in the internet..
