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?

Regards,
Sam
