If it needs to be completely dynamic, then you need something like saxon:evaluate(), and you need to solve the problem with the apostrophes ;-)
One way to do that (and also to protect against code injection) is to generate a call using parameters:
saxon:evaluate("*[@type = $p1 or @type=$p2]", 'mc', 'ti')
But I wonder if it does need to be completely dynamic? Would
solve the problem?

Hi
I need to create predicates like the following dynamically:
[@type = 'mc' or @type='ti']
I need the full content of the predicate to be created in a variable "x", to be inserted in the predicate like:
//qa [$x]
I have tried using saxon:evaluate() but run into problems with apostrophes. What to do?
Cheers Jesper Tverskov
