in thread regex for strings with escaped quotes

The regex is:


which contains no capturing groups, hence $1 isn't populated. In my first bit of code, in the regex I added an extra set of parentheses, /($RE{delimited}{-delim=>'"'})/, so there is a capturing group there. That's the equivalent of:


Alternatively, you can take the first regex above and just change the non-capturing group (?:...) that surrounds the entire expression into a capturing group:


Or, since you said you wanted to capture the stuff between the quotes, change that non-capturing group into a capturing one:


Plus, there's a bunch of simplifications that could be made to the first regex above anyway (really just removing unnecessary groups):

/ \" [^\\\"]* (?: \\. [^\\\"]* )* \" /x

and just add capturing groups to that as needed.

    Ahh - I did not pay attention that you introducded a new capturing group by puttting the regex into an extra pair of brackets.

    Now it all makes sense - many thanks.

    I've never used Regexp::Common before but it seems to contain useful stuff - I see a bright future for it in my Go-Programs :-)
