incrementing dates with variables?

List:
I have a problem that is just outright bugging me. What I need to do is take the arrivalDate which is a param at top-level and then depending on how many nightlyRates are under NightlyRates element in the XML, increment depending on how many nights there are.

I know that I'm pbly thinking about this the wrong way, any suggestions, good or bad are welcome.
Ideally I would like the following format:

first date  second date   third date
   price          price             price

and so on...

Thanks!
