What i was doing obviousl;y does not work because it needs to be a nodeset.
Can any one tell me how to do this without using the extension : nodeset.
Its is  MANDATORY that I  DO NOT USE the extension nodeset.

YOU ARE NOT OBLIGED TO! :{)}


I hope you find the example below useful. It is based on the principle that a stylesheet can read itself as if it were a source node tree by passing an empty string to the document() function.
