How to parse a ping result with regex

Question

What I want is to parse the result of a ping, line by line. It's a bit tricky for me and tried a lot of things but well... I'm using the ping on Android.

For example:

PING google.com (173.194.35.9) 56(84) bytes of data.
64 bytes from mil01s16-in-f9.1e100.net (173.194.35.9): icmp_seq=1 ttl=52 time=33.0 ms

--- google.com ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 33.086/33.086/33.086/0.000 ms

On the first line, I want the Ip address, the "56(84) bytes of data". On second line "64 bytes", 1,52,33.0 ms etc.

If a ping an IP directly, it changes a little bit

PING 192.168.0.12 (192.168.0.12) 56(84) bytes of data.
64 bytes from 192.168.0.12: icmp_seq=1 ttl=64 time=0.134 ms

--- 192.168.0.12 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.134/0.134/0.134/0.000 ms

But should work too !

And if I have a little explaination with an answer, it would be cool !

Thanks so much!

Description

This expression will capture IP, bytes of data, bytes, ICMP_SEQ, ttl, time. I couldn't find etc.

^PING\b # match ping
[^(]*\(([^)]*)\) # capture IP
\s([^.]*)\. # capture the bytes of data
.*?^(\d+\sbytes)  # capture bytes
.*?icmp_seq=(\d+)  # capture icmp_seq
.*?ttl=(\d+)  # capture ttl
.*?time=(.*?ms)  # capture time
.*?(\d+)\spackets\stransmitted   # the rest of these lines will capture the other portions of the ping result
.*?(\d+)\sreceived
.*?(\d+%)\spacket\sloss
.*?time\s(\d+ms)
.*?=\s([^\/]*)\/([^\/]*)\/([^\/]*)\/(.*)\sms
