Repeated capturing groups in regex when only last match is allowed (workaround)
I got an string like
*hello world,hello2 world2,hello3 world3,..., helloN worldN *
I want to match repitedly hello worlds and capture only hello words in a global (/g) level for a multiline string, where that pattern is founf occasionally
If I define a repeated group with hello captured *(?:(w+)sw+,?)+* only the last helloN is matched due to http://www.regular-expressions.info/captureall.html
If I define a capturing group looking for the repeated hellos *((w+)+)* Then my problem is that the match is not done, as it is checking against *hello world,hello2 world2,hello3 world3* or everything within two asterisks with that pattern
The result should be
- hello hello2 hello3 ... hello n
I think the key is finding a way to force to match the repeating group whereas the captured group is returning multiple outputs
use this:
(?<=[,*])(w+)(?=sw+[,*])
