PXTL is a specification for a templating format mixing XML-based markup languages with Python code. It is especially suitable for use in a web application's page output stage. *Another* web templating system? Yes, I'm afraid so. PXTL does have a few features which are (as far as I know) unique, though: - it's a pure-XML format, which should make syntax and nesting errors very easy to debug (especially with a syntax-colouring, well-formedness checking text editor); - output can automatically be translated into legacy (non-XML) HTML or non-tag-based formats; - a number of XML processing instructions for including content in various common escaping formats; - elements from a separate namespace for flow-control (if, for, def, etc.), to allow a Python code hierarchy and XML markup hierarchy to be mixed cleanly. I'm pleased to announce the second draft of the PXTL specification, and I'd appreciate any feedback on it from web and XML authors (in particular those familiar with XHTML) either by mail or to c.l.py. http://www.doxdesk.com/pxtl/ A reference implementation will be made available (under some manner of open-source licence) some time in the next few months, taking into account any comments received. cheers, -- Andrew Clover mailto:and@doxdesk.com http://www.doxdesk.com/
