Regex find single N occurrence of ',' to replace
I’m wanting to do something seemingly simple, but I’m having a hard time creating the expression.
Say I have this text:
I’d like to select say the 4th comma and only that character:
I’m probably overlooking something fundamental in regex.
I’d like to select say the 4th comma and only that character
This seems overcomplicated, but it also seems to do the job:
Thank you, regex seems to have its limits in regards to simplicity in certain use-cases.

The regex was able to express in 28 characters something you used 341 characters to describe. It used only 5 or 6 different elements of syntax to express that. It’s incredibly simpler than what you would have to write in raw C (ie, no external libraries) or assembler to do the same thing. Or even the English-based algorithm you’d have to write down to accomplish the same task, accounting for all the same edge cases that the regex syntax is naturally handling.
