I have already succeeded in what I want; but that was Manual exercise, by Editing in a Notepad. So not possible to do it for thousands of files and thousand of times So now trying to do it through a code.

I don't think its always necessary to understand the entire language / format first to achieve some task. If it would have been so, it will take a month to first understand the format and do further task on it.

Thanks Anyway.
Regards
Harsh
