Re: Building a calendar

Ken,

Wow! You just saved me a lot of trouble.

I changed the XSL a little to match my intentions a bit more. I'm going to
change it further to make it work with my broader system. I'll probably make it
emit my XML TABLE model or simply use the HTML namespace. Either way, it will
work wonderfully. I've attached my slightly changed instance and the XSL.

The calendar was the only part of my Profesional XML Authoring course that was
hindering me from delivering it all in XML. The September offering should be
all-XML. Sounds good to me!

Thanks again (wow!),

Richard.
