How does a template instantiated? - XSLT

How does a template instantiated?

- The template is used to instantiate the part of the result tree that is separated from the source tree.

- The structure of the result tree remains different from the source tree due to the parent child relationships.

- Elements are taken from the source tree and used in the result tree and a relationship gets created.

- The elements can be added using the methods like filtered, reordering and its arbitrary structure.

- The transformation can be easily done in using the XSLT used for stylesheet in XSL language.
