[jQuery] autocomplete plugin - newbie question

[Casey Wise]

You guys, I really dig working with jQuery, very powerful stuff.  I've
been trying to implement the autocomplete plugin but I don't know how
to ask this question, or google what I need to know.

We have 6000 staff (records) here on campus and we want to be able to
search them by their first & last name.  I have to use an XML web
service that's controlled by another group.  Getting the output
changed would be near impossible, so it's gotta come out this way.  I
curl that XML into a PHP.  I pass that php a "GET" argument of name,
in this instance "casey" and below is what it comes back with.

Can this be done with XML like this using the autocomplete plugin
