Re^2: How to store matched $1 values one by one to array?

[AnomalousMonk]

A minor variation using the  \K (5.10+) and  s///r (5.14+) regex operators, and no capture groups. (Note: I use  \x22 instead of  " (double-quote) in the  s///r substitution because the Windoze CLI gets a little freaky over unpaired double-quotes.)

>perl -wMstrict -MData::Dump -le
"my $line =
   q{xxx:agent_id=>foo,yyy:agent_id=>b\"a\"r,zzz:agent_id=>\"baz\",qqq
+};
 ;;
 my @agents =
   map s{\x22}{}xmsgr,
   $line =~ m{ :agent_id=> \K  [^,]+ }xmsg;
 ;;
 dd \@agents;
"
["foo", "bar", "baz"]
