- How to match, but not capture, part of a regex? - Stack Overflow
The key observation here is that when you have either "apple" or "banana", you must also have the trailing hyphen, but you don't want to match it And when you're matching the blank string, you must not have the trailing hyphen A regex that encapsulates this assertion will be the right one, I think
- If two cells match, return value from third - Stack Overflow
=INDEX(B:B,MATCH(C2,A:A,0)) I should mention that MATCH checks the position at which the value can be found within A:A (given the 0, or FALSE, parameter, it looks only for an exact match and given its nature, only the first instance found) then INDEX returns the value at that position within B:B
- Regular expression to stop at first match - Stack Overflow

- python - Check if string matches pattern - Stack Overflow
As others have said, re match() checks for a match only at the beginning of the string re search() can mimic that too by prepending \A to whatever pattern used On the other hand, re fullmatch() checks if the entire string is a match, which can again be mimicked by re search() by prepending \A and appending \Z to whatever pattern used Below
- Regex: ignore case sensitivity - Stack Overflow
G[a-b] * i string match("G[a-b] *", "i") Check the documentation for your language platform tool to find how the matching modes are specified If you want only part of the regex to be case insensitive (as my original answer presumed), then you have two options:
- OR condition in Regex - Stack Overflow
For example, ab|de would match either side of the expression However, for something like your case you might want to use the ? quantifier, which will match the previous expression exactly 0 or 1 times (1 times preferred; i e it's a "greedy" match) Another (probably more relyable) alternative would be using a custom character group:
