Question

How to fix this regex in order to get the mentioned outcome ?

regex: (0(?:[0-9]|[A-F]){3})(\"\*?(?:SIA-DCS|ADM-CID|NULL)\")(\d{4})(R?(?:[0-9]|[A-F])*)(L[^#]*)(#[^\[]*)(\[[^\[]*)(\[(?:M|V|P)(?:[^\[])*])

string: LCR005B"*ADM-CID"9876R579BDFL789ABC#12345A[4D32FC2B12345A|113002065][Vanydata][M1234567890AB][Panydata]

outcome should be:

1. 005B
2. “*ADM-CID”
3. 9876
4. R579BDF
5. L789ABC
6. #12345A
7. [4D32FC2B12345A|113002065]
8. [Vanydata]
9. [M1234567890AB]
10. [Panydata]

Later edit:

This currently outputs:

1. 005B
2. “*ADM-CID”
3. 9876
4. R579BDF
5. L789ABC
6. #12345A
7. [4D32FC2B12345A|113002065]
8. [Vanydata]

Answer 1

This is your regex:

(0(?:[0-9]|[A-F]){3})
(\"\*?(?:SIA-DCS|ADM-CID|NULL)\")
(\d{4})
(R?(?:[0-9]|[A-F])*)
(L[^#]*)
(#[^\[]*)
(\[[^\[]*)
(\[(?:M|V|P)(?:[^\[])*])

You do have only 8 capturing groups, none is repeated, why do you think this should output 10 groups?

OK, Because of the (?:M|V|P) of the last group, it would be able to match the content of the 3 last square brackets, but this group is not repeated, so it will match only the first one.

You have 2 possibilities.

1. Put a quantifier behind the last group

   (0(?:[0-9]|[A-F]){3})(\"\*?(?:SIA-DCS|ADM-CID|NULL)\")(\d{4})(R?(?:[0-9]|[A-F])*)(L[^#]*)(#[^\[]*)(\[[^\[]*)(\[(?:M|V|P)(?:[^\[])*])+
   

   or

   (0(?:[0-9]|[A-F]){3})(\"\*?(?:SIA-DCS|ADM-CID|NULL)\")(\d{4})(R?(?:[0-9]|[A-F])*)(L[^#]*)(#[^\[]*)(\[[^\[]*)(\[(?:M|V|P)(?:[^\[])*]){3}
   

   this will now match the string till the end, but there are still only 8 capturing groups and the content of the last one is now not “[Vanydata]” anymore, its the last match of this group “[Panydata]”

2. Add two more groups to your regex

   (0(?:[0-9]|[A-F]){3})(\"\*?(?:SIA-DCS|ADM-CID|NULL)\")(\d{4})(R?(?:[0-9]|[A-F])*)(L[^#]*)(#[^\[]*)(\[[^\[]*)(\[(?:M|V|P)(?:[^\[])*])(\[(?:M|V|P)(?:[^\[])*])(\[(?:M|V|P)(?:[^\[])*])
   

   This does now have 10 capturing groups and the result is as you expected. If the Starting letter of those 3 last groups is always the same for each group you can simplify it to

   (0(?:[0-9]|[A-F]){3})(\"\*?(?:SIA-DCS|ADM-CID|NULL)\")(\d{4})(R?(?:[0-9]|[A-F])*)(L[^#]*)(#[^\[]*)(\[[^\[]*)(\[V(?:[^\[])*])(\[M(?:[^\[])*])(\[P(?:[^\[])*])
   

   See it here on Regexr

Update

You can make something optional by adding a question mark after it

(0(?:[0-9]|[A-F]){3})(\"\*?(?:SIA-DCS|ADM-CID|NULL)\")(\d{4})(R?(?:[0-9]|[A-F])*)(L[^#]*)(#[^\[]*)(\[[^\[]*)(\[[VMP](?:[^\[])*])?(\[[VMP](?:[^\[])*])?(\[[VMP](?:[^\[])*])?

See it here on Regexr, hovering over the match shows you the content of the capturing groups.
