Mimicking a SELECT/CASE statement using XSL

From: gadrin7@---.--- (--------)

as a newbie to XSL, is it possible to mimic a SELECT/CASE statement
using
XSL?

I tried a quickie and I kept getting errors either using PARAM or
WITH-PARAM
in the wrong place or VARIABLE. I ended up using .createProcessor and
doing
all the work behind the scenes in my programming language, then using
the
.addParameter to pass the values.

I wanted to select data, then set variables using XSL:CHOOSE and
XSL:IF based
on the values found in the data, then further alter these farther down
in the XSL with math.

pseudo-code:

xml:
<main class="1">

XSL Logic...

if class == 1
 
  xsl-var1 = 10
  xsl-var2 = 20

else

  xsl-var1 = 50
  xsl-var2 = 60

endif

myNewNumber = "value-of xsl-var1 + value-of xsl-var2"

'convert myNewNumber to kilograms (was pounds)

myNewNumber = myNewNumber * 2.2

etc, etc.

I'm not sure the value of a XSL:VARIABLE can be redefined.

sorry for the fuzziness, any help is greatly appreciated.
