How do I resolve /etc/ssh/sshd_config using nre?

[zhouhaiming]

# cat /etc/ssh/sshd_config

... Port 22 #AddressFamily any #ListenAddress 0.0.0.0 #ListenAddress :: ... 
X11Forwarding yes Port 10022

my nim code :

import nre import streams

let fh = newFileStream("/etc/ssh/sshd_config", fmRead)

var
    fhContent: string = ""
if not fh.isNil:
    fhContent = fh.readAll() let r = re"(?im)^[ t]*Ports+(d+)$"

for res in findAll(fhContent, r):
    echo res.split()[1]

fh.close

output: 22 10022

How can I use group match?
