Hi, note this simple machine:
%%{
machine sip_uri;
action _start { start = p }
action _stop { stop = p-1 ; value = data[start..stop].pack('c*') ; }
action set_userinfo { @userinfo = value ; puts "---userinfo...@userinfo}---" }
action set_host { @host = value ; puts "---host...@host}---" }
action set_port { @port = value ; puts "---port...@port}---" }
user = [a-z]+ ;
password = [a-z]+ ;
userinfo = ( user ( ":" password )? "@" ) >_start %_stop %set_userinfo ;
host = [a-z]+ >_start %_stop %set_host ;
port = [0-9]+ >_start %_stop %set_port ;
uri = "sip:" userinfo? host ( ":" port )? ;
main := uri '\0' ;
}%%
When I parse: "sip:ibc:x...@mydomain" I get this result:
-------------
Parsing 'sip:ibc:x...@mydomain'...
---host=ibc--- <-------- WRONG !!!
---userinfo=ibc:x...@---
---host=mydomain---
Finished: cs: 13 p: 22 pe: 22
Parsing OK !
-------------
I really don't know why 'host' is set twice. I know that it's due to ( ":"
port )?. In case it doesn't exist in the grammar then 'host' is set just once
(with 'ibc:xxxx' value).
Is there any trick to avoid this duplicate result? I've tryed everything I
know with no success.
Thanks a lot foir any help.
