What am I missing?
2 things. First, you can't have multiple matches (//g) AND have your regex anchored at the start of the string.
Second, the //g will return all the captured matches, so you don't need that last +. In fact, you can't HAVE that last +, or it doesn't work.
my @lines = ("a 1 2",
"b 3 4 5 6",
"c 7 8 9");
foreach (@lines) {
# you can't match multiple times starting at ^!
my @list = m/(\s+\d+)/g; # no last +
print @list, "\n";
}
Of course,
demerphq made a very good point about that regex not being sufficient to match all numbers...
