Hi
Is it possible to load an XML file from a domain that differs from scripts domain with pure javascript and without using a php/asp/jsp/... script as proxy?
Something like xmlHttpRequest but with ability to manage cross domain requests.
Thanks

You can use something called JSONP. I know the name sucks, because it's not really related to JSON. But this requires you have control over the other domain. You need to wrap your XML inside a function call, or assign it to a javascript variable:
func('<xml></xml>');
or
var myxml = '<xml></xml>';
So if your other domain returns one of these two formats, you can use the <script src="http://otherdomain/yourjsonp"></script> syntax in your html to load that data in JavaScript. It's a little hacky but a lot of people use it.

Hi, thanks. but it doesn't help me. actually I need to load other sites RSS and traverse it with pure JS. So I just can read files that are provided by others and that file is XML.

Sorry then it's not possible.
It is possible with yql! (Yahoo did it for you)
Go to this site and simple at the "select from url='xxx' " replace the xxx with your xml url. Use the url created at the text box below and do a simple xmlrequest. You won't have any cross-domain prolems
