Some advice about XML

I am beggining to make an online (flash based obviously!) folio which refers to an XML file for data (folio section, description, job name etc) and images/swfs.

The advice I really require at this stage is, is it worth creating using XML?

and

can someone help me with the structure of the flash file. I understand getting the XML data into flash, but just wondering how (if anyone can help) to duplicate MCs (buttons if you will) according to how many jobs are within a section.

I can always provide more info if this makes no sense, I really appreciate all the help y’all offer ( I am no coder (advanced anyways) )
