I got different results in Perl and Ruby of this regular expression.  Can 
somebody maybe give me a "Ruby Way" solution of this?  The output from 
Perl is what I want.  But I'm currently programming this is Ruby.

In Perl:
#snippet start ==========
sub transform_data
{
    my $data = shift;
    if ($data=~/^[\d\.]+$/) #numbers
    {
        print "Got here!\n";
    }
    else
    {
        print "'$data'","\n";
    }
}

my $data = "patched 3 systems:
134.27.56.237
134.27.59.6
134.27.55.43";

transform_data($data);
#snippet end =========

Output is:
'patched 3 systems:
134.27.56.237
134.27.59.6
134.27.55.43'

---------------------------------------------------------------------------------------------------------------

In Ruby:
#snippet start ============
def transform_data(data)
    if (data=~/^[\d\.]+$/) #numbers
        puts "Got here!"
    else
        puts("'" + data + "'")
    end
end

data = "patched 3 systems:
134.27.56.237
134.27.59.6
134.27.55.43"

transform_data(data)
#snippet end ============

Output is:
Got here!

Now why would it match in Ruby?  Am I missing something here?
