I need a variable whose value can be changed based on the if conditions.
That's basically saying that you need to be able to pass c syntax to a
XSLT compiler. That doesn't work.
The expressive power of declarative languages in which variables do not
change there values once bound is the same as that of imperative
languages with mutable variables. So you can't "need" to change the
value of a variable.
If you said what transform you need to do someone wiould most likely
show you how to do it without changing the value of a variable, or as is
often the case, without using a variable at all.
Variables in XSLT have lexical scope and always have a value within that
scope. i see though you say

Not sure here whether you mean empty node set or empty string,

this seems to say you want to set outputVar1 to being both $inputVar1
and $inputVar2 ?
