Hi everyone,
Is there such a thing like "geolocation" module in Kamailio? (or something related to it i.e. [1] [2]).
Thanks, Stefan Mititelu

if it is just about carrying the geo location data through the proxy, then Kamailio can do that.
If you need to do some kind of processing based on geolocation data, then describe a bit more about what you want to achieve, kamailio has a lot of configuration file tools that may help (e.g., xml parser with xpath support -- xmlops module).

Yes, I am thinking of the capability to extract that geolocation data from the xml (when the "Geolocation-Routing: yes").
Consider the example from the section 5.1 from [1]. Suppose I want to extract "gml:pos32.86726 -97.16054</gml:pos>" data and do some processing with it: - save the initial value of this call - compute the value difference relative to the initial value (as geolocation data is received for further messages) - trigger something when a certain difference is reached (e.g. log a message)
Can I approach this somehow with current Kamailio?
Thanks, Stefan
Hello,
you should be able to extract the value of gml:pos node using the re.subst transformation over $rb variables:

I noticed we have functions only to append, set and remove a part of multipart body. I plan to add the function to get a content of a multipart body, that will make it work then with xmlops module for this particular case.
Cheers, Daniel

Thank you Daniel, the "get" function from textops worked for me with a small index change for the end buff when mode == 1, for get_body_part_helper() function (I'll do a pull request for the changes).
I've tried with the attached message file using sipsak and the following config additions:
... modparam("xmlops", "xml_ns", "pos=pos-namespace") ... if (is_present_hf("Geolocation") && is_present_hf("Geolocation-Routing") && $hdr(Geolocation-Routing)=~"yes" && has_body("multipart/mixed")) { get_body_part("application/pidf+xml", "$var(geobody)"); xlog("geobody is $var(geobody)\n");
$xml(posxml=>doc)=$var(geobody); $var(posX)=$xml(posxml=>xpath:/pos:position/pos:x/text()); $var(posY)=$xml(posxml=>xpath:/pos:position/pos:y/text());
$var(posX)=$(var(posX){s.trim}{s.int}); $var(posY)=$(var(posY){s.trim}{s.int});
xlog("LOCATION X IS: $var(posX)\n"); xlog("LOCATION Y IS: $var(posY)\n"); } ...
