Text file manipulations

[AkshatTangri1]

Is there a way to find the count of repeated words in a text file at a specific position . Like I want to find the count of 12345678 at pos 1-8 in the below text file . 12345678546 12345678965 12345678485 12345678987

There's probably a regular expression to do that elegantly but you may be as well doing it crudely with a collection loop and a decision stage.
