I would really like to know why my regex is not working. So here is what the text result of the regex should be.įROM: This line is too long. Here is that code that is grabbing too much. I know there is a relatively simple regex solution for this that I am blanking on, but in my searches of 'Find Nth instance of pattern on a line' type regex answers, the regex that has been closest to what I want is also matching everything before that 5th whitespace on a line. A Perl regular expression replace cannot do mathematical operations and string to integer and integer to string conversions like finding a number string, converting the string into an integer value using decimal system, modify the integer value with a mathematical operation, convert the resulting integer value to a string and replace the found.

On the REPLACE line in Notepad++, I think an would generally do the trick, and it is just the FIND pattern that is giving me problems. I want to match only the nth (let's say 5th) whitespace character on a line and then replace that space with a line break (so that all my lines essentially have no more than 4 words / 4 spaces).
