in thread A regex that only matches at offset that are multiples of a given N?

Because with it, it only matches the first match; not any second or subsequent properly aligned matches?:

print "$-[0]: $1" while $a =~ m[(?:.{4})*(?=(aa..))]g;; 0: aawx 404: aawx 405: aadz 481: aadz print "$-[0]: $1" while $a =~ m[^(?:.{4})*(?=(aa..))]g;; 0: aawx print "$-[0]: $1" while $a =~ m[(?:.{4})*(?=(gg..))]g;; 0: gghn 208: gghn 211: ggyj 955: ggyj print "$-[0]: $1" while $a =~ m[^(?:.{4})*(?=(gg..))]g;; 0: gghn

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
