Well, as I have a pretty solid hold of XHTML, I think it's time to focus once more on XML and it's companion XSL. In addition to learning the language itself, I have a couple of projects which I will be creating to reinforce the lessons.An alternate version of this site (and perhaps my other ones as well) should be challenging as I will have to wrangle with layout issues, markup issues and information architecture. It will also encourage me to learn more about the interactions of PHP and XML.A Flash app which pulls XML docs as a new interface for Apocalyptic Dreaming. This should turn up some interesting challenges as well.I have a number of books about XML, most of which were given to me; I'll post info about each in the next few days as time allows.
