Building block for xml based technologies.

DOING

Input is a XML

XSLT Processor

Can produce another xml

Xslt file needed for

processing

Can produce a

ELEMENT

This is the first element of the xslt which defines

the version and Namespace of the xslt.

This is useful you want to change the structureof the element i.e add or remove its attributes .

It is being used to process all the nodes in the in

the node-set according to the XSLT instructions

This is used to specify the sort order of the node-

sets .

This can work with
