Hello,

the line you try to match is:

m=audio 64192 RTP/AVP 107 0 8 18 101

However, the subst does not have rule to match 'RTP/AVP' string:

{re.subst,/^(.*)m=audio ([0-9]+) ([0-9 ]+)\015\012(.*)$/\3/s}

It is looking for digits and white spaces after m=audio.

Cheers,
Daniel

An example $rb body would be:

v=0#015#012o=- 5 2 IN IP4 192.168.3.100#015#012s=

Hello,

I am trying to match a multi-line psuedo variable, i.e. $rb

However I am wishing to pull out the payload values

i.e.

"0 18 101"

"18 101"

etc.. etc...

I am having trouble matching this. Any help would be appreciated.

One part that is giving me trouble is that it seems xlog prints out \r\n as \015\012

do you print xlogs to syslog or to terminal?

I am not able to successfully just pull out the "payloads"

I have tried many different variations, however here is one of my latest:

xlog("L_INFO", "[$ci] $(rb{re.subst,/^(.*)m=audio ([0-9]+) ([0-9 ]+)\015\012(.*)$/\3/s})");

Can you paste the body you worked on and the output you got? Will help understanding what happens and maybe give some hits, being easy to reproduce and test ourselves.

Cheers,
Daniel
Any help / input is greatly appreciated, thank you ahead of time!

Happy 4th of July (for those who celebrate)
