I'm no grand pooh-bah of melbourne.pm list etiquette however it sounds
like a pretty reasonable thing to be doing to me.

Sounds like a job for Perl, do you have any specific questions about

... you want to abstract the markup generation from your code as early
as you can. If you find yourself printing out HTML from within Perl then
