Hi,

The re.subst transformation can be used on variables to extract data. http://www.kamailio.org/wiki/cookbooks/devel/transformations#resubst_expression

$rb is the variable that contains the request body, but you can use $var or $avp variables if doing multiple operations.

$var(data) = (int)$(rb{re.subst,/^rate is ([0-9+).*$/\1});

Regards,

Hugh

Subject: [SR-Users] Text Operations on a Message

Hi list,

How can I extract a specific part of my message body?

I know that "textops" has the function "search_body(re)" but it returns True/False upon finding "re" in the body of the text, how can I return the actual text that regular expression matches?

As an example, my message body is

rate is 172#012

I want to extract the number "172" out of this.

Thanks

Alireza
