I've been working with the XML/XPath/XSLT/CSS combination for applying styling since 2007, starting with my first ideas about it in this post: http://lists.w3.org/Archives/Public/www-style/2002Dec/0074.html I would recommend it; It's simple to create, simple to edit, simple to maintain, simple to read, and simple to share. You'll have to make a mix of applying it inline and through regular CSS selectors. Inline isn't pretty for SEO, so some 'intelligence' would be nice (though I hadn't the time and motivation to build this). I'll consider sharing my framework, but there's no really need to cause you can create it in just a few hours depending on what language you use. PHP is very simple using the default DOM-modules+XSL(T). Good luck! -----Original Message----- From: Thomas Lord [mailto:lord@e...] Sent: maandag 23 juni 2008 21:05 To: Micah Dubinko Cc: Costello, Roger L.; xml-dev@l...

The parsimony of sharing syntaxes, semantics, and implementations would likely work well. How could anyone seriously object, were it practical to make that change? (The impracticality is serious, though: we'll have browsers standardized on the current syntax for quite a while to come I'm sure. Changes that cause more browsers to implement CSS *correctly* are surely a higher priority :-) Were one to attempt an XML syntax for stylesheets (and XSLT transform to ordinary CSS syntax) it would be interesting to see if the XML version could use XPath. (Having XPath <-> XML transforms as primitive operations or a standard library in XSLT and XQuery would be handy for this and many purposes.) An XML/XPath solution could (this is quite speculative) be a very interesting tool. For example, given an XML database, libraries of styles could be associated with various parts of some of the schema present in the database. Then, pages could be synthesized on the fly -- along with customized style sheets for those pages. One can imagine systems that let users program up new queries interactively, on the fly, and then then render reports from those queries very smartly - composing various XML-ized style sheet fragments into a complete stylesheet which, as a final step, gets transformed to the syntax browsers like. Micro-formats on steroids, so to speak. -t _______________________________________________________________________ XML-DEV is a publicly archived, unmoderated list hosted by OASIS to support XML implementation and development.
