in thread regex capturing problem

Doesn't really explain why I get only the last two parts as my regex started whith '^' and therefore can't just start matching in the middle of the string...

But the correct answer has already been given (thanks, erikharrison). I just wasn't aware that ()+ gives you just one item, no matter how often it matched.

    The point is not whether it can start matching in the middle of the string but whether it can start _capturing_ in the middle of the string. By adding a + to the first part you allow the RE engine to effectively ignore the ^ anchor while still forcing it to make a match at the end of the string.

    Actually, it matches all of them, but since it is repeating, it overwrites the first match: 
    $ perl -lwe"q<d'aujourd'hui> =~ /^((\w+')(?{print$+}))+([\w-]+)$/"
d'
aujourd'
$
