Re^3: Perl-Replacement of comma in between the matched Patterns

You still haven't explained what "failed in other cases" means.

It's hard to read in your one-liner (have you tried adding the /x flag to your regexp which allows you to write it over multiple lines, with comments?), but in your second statement it sure seems like you are replacing anything that matches ,(?=[^\[\]]*\[*\{*\}*\]) with | ... you probably need to learn about extracting matches, too.

Remember: Ne dederis in spiritu molere illegitimi!
