RE:  pagination - From PHP To XSL - Recursion ?
Not understanding either PHP or Spanish, I'm a bit disadvantaged here. But
in any case, trying to reverse-engineer procedural code and turn it into
declarative code is usually not the best way to go about things. You often
need a completely different approach. It would be better to describe the
inputs and outputs of your transformation, and work from there.
