Hi Shlomi, Thank you for the pointers. I do want to learn Python as well when I get a chance. This "framework" I'm writing now will automate things to a great extend eventually freeing up loads of my daily operations time so I can focus on more interesting things.
I'm really not expecting the code to be written for me, mere pointers as you did (with some examples would be a plus) is all that's needed for me to look into that and take it further. The example here: http://perl-begin.org/uses/text-parsing/ already helps quite a bit.
