Shuffle postion of letter in a word using XSLT

Exactly.

Ok but why? Could you post some code?

I am not the one who posted Question, ;)

Above comments are right--XSLT is not simplest way to go on this, and only makes sense if you're doing it as a part of an existing transform. And what output are you looking for? Every permutation? If so, sounds like a homework exercise ... though if someone's asking you to do this in XSLT for an assignment, they're torturing you.
