Re: [xsl] A Calendar Project...

["Karl J. Stubsjoen" <karl@xxxxxxxxxxxxx>]

What if I needed 8 weeks of Sundays... so from an XML source of  40 weeks
worth of dates... I'd like to grab 8 of them.  Is this something you would
handle with keys?
I have a working demo of the calendar I've put together thus far, its here:
http://www.meetscoresonline.com/test/calendar.asp
I'm using ASP to build the XML source dynamically... so basically, the
stylesheet simply spits out all the results from the XML source.
