Is this possible in XSL?

Hi;
Is it possible to get all the answers'  item-ids in a way that covers
all the possible correct answer combination. 
For example I have this multiple choice question in XML and the correct
answers are "A" "B" and "H". 
What I want to output is to get all the possible correct answer
combination like this: 
			"ABH | AHB | BAH | BHA | HAB | HBA"

How can I do this in XSL?
Thanks.

Cihan
