I have no idea what you mean. All this regex does is walk the string (char by char) with a 1 char buffer (the last char). When it gets a match (last char not \\ and char eq ') it gets a match and we record the position. This is hardly a regex at all!
Here it is completely C-ified - no regexes in sight. Possibly faster than the original post to boot but I can't be bothered to test.
$str = " '==\\'==' '==5==' '\\'\\'' '\\'3' '\\'' '1' '' ";
my $pos = 0;
my $len = length $str;
my $last = '';
my $char;
while ( $pos < $len ) {
$char = substr $str, $pos, 1;
push @pos, $pos if $char eq "'" and $last ne "\\";
$pos++;
$last = $char;
}
for ( my $i= 0; $i <@pos; $i +=2 ) {
my $begin = $pos[$i]+1;
my $end = $pos[$i+1];
my $str = substr $str, $begin, ($end -$begin);
print "$begin $end |$str|\n";
}
