How to use arrays in xsl

Hi all,
I am facing a problem while writing an xsl.
In my xml I have a comma separated values (csv) list. On each of the
value in this list I want to do some processing. For that I want to
parse the csv string and store it into an array and pass the array to a
separate template from processing. Can we do this in xsl?
