Quite a few people are trying to advise you on good ways to accomplish the task you are talking about, but you seem to be very reluctant about showing exactly -what- you are trying to do.I want to do it because of the mundane practice of going through thousands of files checking the same thing over and over and then inputting slightly different values all day. If I can create a program that can do it for me it will free up my time to pursue more worthwhile things maybe even more money for me.
You might as well be saying, "See I have this play, but I don't know if the script is any good, can anyone tell me?" and not posting any of the play.
Personally my force powers are a bit off these days so I have trouble reading things that aren't around to see.
