Need help with processing a text block with python function

I know this is kind of an org-mode 101 question, sorry, but after searching
docs for a couple of days, I could use a pointer. I want to write a
function in a code block in python or perl that steps through lines of text
and does some complicated reformatting, adding in html bits and such, for a
specialized application. Then I want to be able paste a block of text into
an org-mode file and call this function to walk through it and do it's
stuff, sending the result to an export buffer.

What's the best way to do that, specifically, what should I do with the
text to be processed? Put it all under a single headline and call the
function against that headline? Put it within some sort of begin/end
markers? I need the python or whatever script to be able to step through
one line at a time maybe using it's usual text input functions.

Thanks,
maab
