What are the hooks provided by XSLT?

- XSLT uses the expression language that is defined by XPath and it selects the elements used for processing and generating text.

- It provides the use of conditional processing that includes the path selection and language that can be used in most of the places.

- XSLT consists of two hooks and they are used to extend the functionality of the languages.

- The hooks are as follows:

- Hook1 provide the extension of set of instruction elements that is used in the templates.

- Hook2 provides a way to extend the set of functions that is used in XPath expressions.
