XML-based survey engine

[Sir Galahad]

I need to create a web-app.
It should be a "survey/story container", a sort of guided tour across a
list of question (different kind of question must be supported:
multichoice, one-choice, free answer, result...).

It will be user in Health world to train medical people (nurses,
doctor..) using real case-studies, step-by-step, in order to underline
choices cruciality and importance.

My basic idea is to have an xml file containing survey's structure. And
then a "reader" web-app, divided in 2:
- php "CORE" app
- javascript "PRESENTATION", using for example mootools or prototype

My question is: does anybody have any idea if something like that
ALREADY exists on the web? Either something SIMILAR, that can be
customized to my real case?

Any suggestion will be appreciated...

Tnx!!

I suppose that I can inherit a basic structure from a "story engine"..
does anybody knows something in that field?
