JavaScript, JSONP and reading XML from cross-domain

Question

in my JS project I need to load data from cross-domain. (JavaScript sits on domain A, the data comes from domain B)

I have a solution that uses JSONP but I really ne

Answer 1

The whole idea with JSONP is that the response must be executable as script. So sure, you can pass XML data back, as long as it's valid Javascript - for example, the server could wrap its response in a string:

myCallback('')

and you'd have to parse it with jQuery:

success: function(data) { 
    var xml = $(data); // now do stuff 
}

This assumes that you control the other server and/or someone who does is interested in formatting their data that way. Otherwise, you're out of luck, and need a proxy of some sort - you might be able to do this with YQL.
