Receiving TAG attribute values in JSP

[Tauqir Ghani]

I am creating a JSP page in which data is received through a TAG
library. e.g the value of the variable XYZ is given by the following
tag line.

<template:variable name="XYZ">

I have to do some processing on the variable XYZ before I display it.
Can I do an assignment like

<%String MyString=%><template:variable name="XYZ"> <%;%>

or is there an alternate way of receiving the variable values in java
or javascript from the JSP tags.

Thanks in advance
