[as-php-xml] Trying to find a flexibleway to store data

Im working on a concept wich could be described as an online portofolio database.

The structure is build in Flash, and works fine. Now I need a couple of hundred people to subscribe their data, fast and flexible.

I’m relaxed with Actionscript, and like to read and throw around data from XML.

Concidering the points above, I decided to try to following:
[color=navy]Structure in actionscript - parse each porofolio in a seperate XML, doing this with PHP - create 1 big XML for the search-topics…[/color]

Does this make any sense?
