Mike pointed out how un-pretty the knight's tour is in XSLT. I agree;
I didn't look at it closely, but it did look ugly.
However, I think there is a crucial difference between XSLT 1.0 and
LISP, Scheme, Haskell, and the other FP "usual suspects".
In most FP langs, I can define a function to return a value. In XSLT
1.0, I can't do that; I can only add nodes to the output tree of XML or
not. This complicates things quite a bit, because I need to keep
calling templates (functions) until I reach a condition in which one of
them outputs a result and/or calls no more functions. With other FP
langs I can check the return value of a call to a function, and do or
don't do something from there based on the result.
XSLT 1.1 fixes this problem, as I understand it.
But perhaps my understanding is flawed here. Can I somehow use a
variable in XSLT 1.0 to return a value from a template? How would that
work?
