Passionate Development From Journeyman to Master

XML, XSLT, XPath, but how???

Is there a framework out there using PHP that somehow mimic the way of Java using XML for the data and then XSLT for the layout.. err was it Java?
There’s got to be a way to improve our framework, make it more robust but at the same time easier and clearer for people to use it! Hm might develop into an open source project.. but then again, what for, we’ll lose our competitive advantage.
