Having some difficulties figuring out how to create regex that adjusts to the number of groups.
I can have any number of parts ranging from 1 to 4
I tried this regex however it only returns the correct values if it has 4 capture groups, no more no less.
I tried the below regex however it does the same
is there regex logic that is flexible to the number of capture groups in a string? I would like to capture string that have groups up to 4 but may have 3 or 2.
any help would be highly appreciated.
Something like : ^(.+)\:(.+?)(\/|$)(.*?)(\/|$) (repeating (.*?)(\/|$) to the number of possible results will get you in even numbered fields the results you want. So for 1-4:
You can see the results here: https://regexr.com/3sjh5
I do something similar in which I essentially have a different rule for either 5 or 6 fields. Not sure if there is a more robust way but this should be easy to build from for 2/3/4 fields. As an FYI my deliminator is an underscore.
Check out this thread see if it helps.
