I noticed that in regex if you use a capturing group and you try to use * to match multiple parts of the string will always start matching at the end of the last match for example: "00000" If I use (000)* it will only match the first "000" (range 0-2)inclusive , I want it to match range(0-2),(1,3),(2,4) inclusive.

Any Ideas on how to do this or if it is at all possible:

Thank you,

You need overlapping matches, use `(?=(000))` – Wiktor Stribiżew Mar 09 '20 at 16:52
Oh thank you, I used (0)*(?=(00)) and that work, i guess look ahead can be used to match the next two characters as regex loops through looking for group 1 (0)* really appreciate the help :). – Ali Tawfik Mar 09 '20 at 17:57
