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.
