[OpenSIPS-Users] Extract data from AVP

[Mickael Hubert]

Thanks Ben,
yes I tried this:
$var(toto) = $(avp(aline){re.subst,/.*:(.*)/\1/g}); # delete a=channel:

xlog("line in the SDP body is $(var(toto){re.subst,/(.*)@.*/\1/g})\n");
xlog("line in the SDP body is $(var(toto){re.subst,/.*@(.*)/\1/g})\n");

It works like a charm, maybe there is a better way ...
