I am attempting to create a cursoring subroutine that will allow me to create what I call a slice navigation string.

My script allows for a "&slice=" parameter to indicate what slice to show. This works along with my "&max=" parameter to indicate how many records to show per slice.

What I will have is a $ENV{'REQUEST_URI'} whice will contain the "slice=" string in it along with a number. There are however 3 possibilities; they are: 

     FIRST PARAM: slice=[SOME_NUMBER]&this=that
MIDDLE-ISH PARAM: this=that&slice=[SOME_NUMBER]&that=this...
      LAST PARAM: this=that&that=this&slice=[SOME_NUMBER]

What I am looking for is a regex that would create a pre and post string that would do the equivilant of (using the first example: 

     $pre = "slice="
     $post = "&this=that"

so that I can loop and insert numbers into my new URI 

     slice=1&this=that
     slice=2&this=that
     slice=3&this=that
     ...
     slice=100&this=that
     .....

and so on, and so on. I've been trying to do this myself but have had no luck in getting a regex to address all three scenarios.

TIA
