a parser is a program that i will take some preformatted text, extract
the information from it, and then do work with that information. xml
programs users parses to pull data from between the <> tags.
in your case, you'd have to have some sort of declaration in your code
that sets apart code blocks you want replaced, invent some sort of
system of replacing that code on demand, then write that code that
implements your system. a little difficult, and out of my scope, i'm
sure. unless i spent two weeks with minimal sleep.
