You start by writing some code[1]. I recommend Python, as it's a
wonderful language, easy to learn, easy to read, has lots of
example code, and the folks on this mailing list are ever so
helpful (as shown by answering your last umpteen questions for
which you seem to have not demonstrated a whit of effort towards
solving yourself). However, as you're doing lots of text
manipulations, I've heard Perl and Awk are also good at that sort
of thing[2].
Then once you've written your code, if you have problems with it,
you ask questions here on the list. Post the germane snippet of
code that isn't working quite the way you expected, along with a
detailed description of the problem. Perhaps, if you get an
exception traceback, you include the whole traceback.[3]

[1] Writing code is a difficult thing to do and success may be
limited to people with an aptitude for the thought process. If
programming confounds you, you may want to read any of the
readily available texts on how to program[4], take a class on the
topic, or you may need to hire somebody to write the code for you.
[2] I occasionally do Awk, but try to avoid Perl to the best of
my abilities.
