[sr-dev] Parsing list of headers

Hello all, I am trying to implement RFC 7544 in kamailio.cfg, more specifically to transform Diversion header into History-Info. To do this I need to iterate over all Diversion headers and be able to get all the parameters from it. At first I discovered $di core variable, but I can access only the first header with it. I discovered kamailio selectors but I can't index them with a variable. I came to the point where I want to implement variable indexing to selectors but after I saw this API is quite complex I thought to ask here if there's any other solution to do this?! Thanks, Ionut
