Reading server-side XML with JavaScript and jQuery

Question

Hello, this is quite a simple question hopefully.

Our client currently has a Flash banner ad on their site which they can change the text size, colour, position etc. by editing an XML file. They want to scrap flash and use JavaScript and jQuery. Now, as long as the XML file is at a readable URL I should be able make an AJAX request for the file and use it. Is that correct?

Many thanks

Answer 1

Yes … and No: The URI must be on the same host (and port, etc, etc) or run into the Same Origin Policy.

Answer 2

Yes. http://api.jquery.com/jQuery.get/
EDIT: Of course I forgot about the same origin policy: http://en.wikipedia.org/wiki/Same_origin_policy
