How do i make an XML-RPC call using AJAX?

Basically i am trying to use OpenSubtitles API with an Adobe AIR project i am working on. 开发者_StackOverflow中文版So i want to make an XML RPC call to their server using AJAX. How do i do it ?

Yesterday i tried the same on Python and it was pretty simple.

x1 = xmlrpclib.ServerProxy("http://api.opensubtitles.org/xml-rpc")
response = x1.LogIn("", "", "en", "OS Test User Agent")

Now how do i achieve the same in AJAX ?

XML-RPC has a spec you need to follow. You could do that by reading this: http://en.wikipedia.org/wiki/XML-RPC

Or just use this library: http://www.zentus.com/js/xmlrpc.js.html
