Re: regex: list each ocurrence of a pattern in a line

Meet the "g" modifier.

my @matches;
for (@fields) {
   push @matches, /%%(\w+?)%%/g;
}

Or even

my @matches = map /%%(\w+?)%%/g, @fields;
[download]

The "?" quantifier isn't necessary. I don't know if it's faster with or without it. If probably only matters if the elements of @fields are very long strings, so you might as well leave it out.
