Trying to create a rotating 'testimonial' ticker with AJAX/JQuery

I have an XML file containing different testimonial quotes, including the name of the person they're quoted from.

I have a DIV on my page, and I want it to rotate randomly between these XML testimonials - LIVE (without refreshing).

If this can be done easily in JQuery, that would be even better. I'm just trying to get into AJAX/JQuery, so any开发者_Python百科 guidance would be very much appreciated!

jQuery Cycle will do this easily.
