 This is essentially the core of what xmlsh does, except its based on XQuery not XSLT. But it has lots o' bitty tools you can efficiently script together to work with xml. Its also what XProc does although XProc does so in XML Syntax. So there are already such tools out there ... ------------------------- David A.
