Or do you really mean, you are trying to capture all 4 digit strings
that are not in a string of longer digits? You need to be very explicit
about what you are after.
The example was intended to resolve the ambiguities of my informal description :-) You correctly surmised what I was after.
my @a = ($foo =~ m'(?<!\d{4})\d{4}(?!\d)'g);
And your solution works. Now I'm going to study up on *how* it works!
Thanks, and also thanks to Dave and Gunnar for what appears to be the same solution, and the references to extended patterns and zero-width assertions.
