May be for a start someone can clarify the general rules of engagement in
this battle with regex transformations.
https://www.kamailio.org/wiki/cookbooks/5.1.x/transformations#resubst_expre…
What kind of regex library does this function expect: PCRE, Perl, Java,
POSIX BRE/ERE?
I've used all kinds of regex validators, regex101.com, rexv.org. Some
expressions pass those but do not work in Kamailio. The result is a dump of
the entire $rb.
Much obliged.

Hi there,
May be some regex gurus can help me out. Being aware that regex's are
tricky but not seeing another alternative in this particular case.
Trying to extract MOSLQ field from $rb.
$var(moslq) =
$(rb{re.subst,/.*MOSLQ=([0-9].[0-9])\s+MOSCQ=([0-9].[0-9]).*/\1/s});
Above regex works fine IF body contains a single matching line. However,
if there's 2 lines as in the below example - it return $var(moslq)=0.0, the
last found value.
I need only *LocalMetrics *values, so I tried this regex which works fine
in regex101.com with flag 'multi-line' and *without flag 'global'*, but
doesn't work in Kamailio.
$var(moslq) =
$(rb{re.subst,/.*MOSLQ=([0-9].[0-9])\s+MOSCQ=([0-9].[0-9])[\nRemoteMetrics]?.*/\1/s});
Assuming $rb is as follows:
VQSessionReport
CallID:1ca9258d285a539e3c1048205bf38d41@mypb.net
LocalMetrics:
Timestamps:START=2018-10-29T15:04:38Z STOP=2018-10-29T15:06:13Z
QualityEst:EXTRI=127 MOSLQ=4.2 MOSCQ=4.4
RemoteMetrics:
Timestamps:START=2018-10-29T15:04:38Z STOP=2018-10-29T15:06:13Z
QualityEst:RCQ=0 EXTRI=0 MOSLQ=0.0 MOSCQ=0.0
Thanks in advance.
