How are these books lacking in what you are looking for?

They are not lacking I guess, my bookshelf is lacking :)

"Data Munging with Perl" is new to me, I had never seen that one before, but you can bet I will order it ASAP.

As for your fine book, I have to admit, I skimmed over it several times, but never looked closely enough to see all that it was about. I suppose maybe I should pick that one up as well, unless of course you have some extra copies lying around you wanna give away :)
