I guess I must be using it wrong, or the two routines aren't meant to acheive the same thing. As-is, yours does find and match on the quoted sections and handled the embedded quotes ok -- although it does leave the leading and trailing quotes in place -- but it also matches on the unquoted sections?

I get the impression that we are both acheiving our goals adequately, they are just different goals:)

Testcode

#! perl -slw
use strict;
require 5.008;

my $re_quoted = qr[
    (["'])                                         #'"
    (?{ local $q = $^N })
    (
        (??{
            "(?x:
                [^$q]
                |
                (?: (?<!$q)(?: (?: $q ){2} )+ )
                |
                (?: \\$q )
            )+"
        })
    )
    (?{ $quoted = $^N })
    (??{ "$q" })
]x;

my $re_quoted2 = qr[\G (
        ' (?: \\ . | '' | [^'] ) + '
        |
        " (?: \\ . | "" | [^"] ) + "
        |
        (?: \\ . | [^'"] ) +
)]x;

while( <DATA> ){
    chomp;
    our $quoted;
    print;
    print "\t<$1>" while m[$re_quoted2]g;
    print '';
}
