I wish there was a version of WordPress that based it's templates off XSLT, XPath, and XQuery. Maybe I'll make that a side project, to clone WordPress but use a few better technologies than WordPress does. For the record, I think Wordpress is lovely. Great product. Problem is, the software can't ensure XHTML compliance because it uses the ASP markup model for scripting. It's very flexible, but that doesn't allow for correctness checking. Of course, PHP is a lot easier to understand than XSLT, XPath, and XQuery. And for all I know MySql and PHP don't support those technologies. My view is, the software (WordPress) ought to be written in PHP, but the stuff for users ought to be done in the more obtuse technologies. Yeah, it would mean fewer people would use it, cause it'd be more of a pain to learn. But dammit, it's logically correct and elegant. And as everyone in programming knows, that's what matters to us software engineers.
