[sr-dev] [ser-dev] re.h - subst_str ussage

Hi guys, I am trying to 'search&replace' some patterns in message body but unfortunately with no result (but bunch of errors). First of all I am trying to perform regex substitution as one that can be seen at https://regex101.com/r/vF1kZ7/1 Since I have regular expression I am trying to convert it so it will work with `sub_str` function from re.h Here is my attempt: https://gist.github.com/ivanbarlog/1b552b57e89bf4670872#file-test-c-L12 I had quite lot of errors but last error I am getting is that `subst_parser` cannot find separator https://github.com/kamailio/kamailio/blob/master/re.c#L240 Since the `struct subst_expr` is not parsed right the next error is segfault in `subst_str` function. If someone can explain me how exactly I should use `subst_str` function with my regex I'll be really grateful. Little example code would be also great. Thanks in advance
