Note that another, perhaps safer, way of capturing everything after "agent_id=>" up to but not including a comma is to use use a negated character class ([^,]+) meaning one or more of anything that isn't a comma rather than a non-greedy match of anything (.+?). You can also populate your array, let's call it @agents, in one fell swoop by using a global match (g flag) and a map within which we substitute away the double-quotes.

$ perl -Mstrict -Mwarnings -MData::Dumper -e ' > my $line = > q{xxx:agent_id=>foo,yyy:agent_id=>b"a"r,zzz:agent_id=>"baz",qqq}; > > my @agents = > map { s{"}{}g; $_ } > $line =~ m{ :agent_id=> ( [^,]+ ) }xg; > > print Data::Dumper->Dumpxs( [ \ @agents ], [ qw{ *agents } ] );' @agents = ( 'foo', 'bar', 'baz' ); $

I hope this is helpful.

Cheers,

JohnGG
