Loading the links from php or xml files to flash

Hi,

I have an organizational chart like animation in which there are 27 buttons,each button is linking to a separate .htm file. There is no problem doing that as I can apply get url over the button. But my problem is the links are going to be changed very often and the person who will be doing that does not know flash,so if I give the links in flash then it will be difficult for him to change the links. That is the reason I want to get the links through some php file.
**So my question is can I store all the links in a php file and connect them to the flash file so that there is no need of opening flash file at all as the editing can be done in php file it self. **

I am not sure whether it is possible in php,so for that matter even if it can be done in XML that will be fine with me as the person who will be changing it knows XML and PHP very well.

Any help would be highly appreciated.
