perlbeginneraaa,

I agree with kcott's assessment; based on your question your script seems to be performing its intended function as expected - in fact, I even took it a step further to apply it to the text file you mentioned in your question.

The result of which looks like OK - I can't post the result here as it's way too long...

However, could you be more specific as to how its result fails to meet your expectation(s)?
