Yes, we do seem to be miscommunicating a bit.

I did not infer the details of your MySQL template system from what you had
said so far. But now you've explained it a bit more and I think I see where
you are coming from a bit better.

We did both observe or agree that iCalendar/vCalendar files were easy to
They also have the repetition issues solved.  I stated that the way I would
things would be to use them as the source.  And to generate the HTML from
that.  I did not say you had to do it that way.  Regardless of which
you choose to go, a tool to build iCalendar from HTML appeared to be a good
first step, so I took a hack at that.

If you want a good generalized to/from iCalendar tool that'll handle a lot
of the niceties for you better than your improved version of my hack,
perhaps this would be a better tool:
