Ken, Thanks for the quick response. I have one more question. How can I maintain a map of java class name to output element name in the XSL and use the map to generate the output element name whenever I find a xsi:type attribute in the input xml. Example Class output element name com.integral.Car.BMW bmwCar com.integral.Car.Buick buickCar Input xml: <cars> <javaobject xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="java:com.integral.Car.BMW" attr1="123"> : </javaobject> <javaobject xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="java:com.integral.Car.Buick"> : </javaobject> </cars> Expected output - <cars> <bmwCar attr1="123"> : </bmwCar> <buickCar> : </buickCar> </cars> Subramanian -----Original Message----- From: G.

Synthesize the new element's type from the attribute value, then strip the attribute. Note the translate() function is handy for what you need to do. It is common to neglect re-synthesizing all of the elements because of the ancestral namespace declarations adding namespace nodes to the elements in the source node tree. It is also common when looking at this problem to be incorrectly thinking about "changing the markup" instead of thinking about the node trees created from the source markup and used to create the output markup. A working example is below. I hope this helps. ..............
