[xsl] Splitting string

["Rui Alberto L." Gonçalves <rui-l-goncalves@xxxxxxxxxxxxx>]

Hi all,
I have a string like:
/this/is/a/test

and I need to create a template that will output:
/this
/this/is
/this/is/a
/this/is/a/test

I think this is not so simple as it looks at first glance.
Does anyone have an idea how to solve this problem?
Thanks for any help.

Rui
