Hi,
       I have xsl variable which holds the following uuid value
(550e8400-e29b-41d4-a716-446655440000) which has '-' at 9-14-19-24 positions.
I want to go these positons 9-14-19-24 and replace the characters '-' with
zero's.
     Is there any function such as replace(position
values,character,replace character) available in xslt.
