This question is probably a bit low-brow compared to the normal
discussions of type systems, rank-2 polymorphism... Anyway, here
I'm working on getting up to speed on haskell in general and HaXml
in particular. I read through the ICFP paper that came with the
distribution, but it was a bit dense for a beginner. Is there anything
out there that is more oriented towards people who are less fluent in
haskell? I think that my problem may be a lack of understanding of the
whole idea of what combinators are and how they work.
What I would like to do is something like the Xtract tool that comes
with HaXml, but to select an element based on the path criteria
specified (as Xtract already does), but that also satisfies an arbitrary
predicate function that I would specify (e.g. a function that normalizes
case and then tests for equality, regexp match, etc.).
If anybody can help out on either front, I would greatly appreciate
