Re: regex capturing problem

because your RE is looking for a "word" (alphanum chars) ending in an ' followed by a word (with possible hyphens) immediately followed by the end of line. this is not the case for "d'aujourd" as there is no end of line. the RE skips this and moves on to "ajourd'hui" which is followed by end of line - ergo a match.

what I believe you want to do is match all wordparts followed by an ' or the end of line like so:

@words = $word =~ /(\w+)['\z]?/g;

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. pike	[reply]

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. larryk perl -le "s,,reverse killer,e,y,rifle,lycra,,print"	[reply]

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' $` [download] p	[reply] [d/l]
