我有一个很长的字符串，但我只对两个变量 state 感兴趣和callee_contact以及他们的值(value)观。

dialog::hash=2089:3329 state::4 ref_count::2 timestart::1471200133 timeout::130932077 callid::TVO3l_3-n-gAYdlXqlFHGg.. from_uri::sip:1010@192.168.10.5;transport=UDP from_tag::c279ef54 caller_contact::sip:1010@192.168.10.10:58055;transport=UDP caller_cseq::1 caller_route_set::caller_bind_addr::udp:192.168.10.5:5060 callee_bind_addr::udp:192.168.10.5:5 060 to_uri::sip:4646644@192.168.10.5;transport=UDP to_tag::yBr2aQBNHSZge callee_contact::sip:4646644@192.168.10.10:5080;transport=udp callee_cseq::0 callee_route_set::dialog::hash=3480:8第766章 状态::2 ref_count::2 timestart::1471200092 timeout::130932077 callid::--8J4085lgGwUqLlr0LUEw.. from_uri::sip:1010@192.168.10.5;transport=UDP from_tag::7d327878 caller_contact::s ip:1010@192.168.10.2:58055;transport=UDP caller_cseq::2 caller_route_set::caller_bind_addr::udp:192.168.10.5:5060 callee_bind_addr::udp:192.168.10.5:5060 to_uri::sip:4646 644@192.168.10.5;transport=UDP to_tag::X2y98UtHmg9Xj callee_contact::sip:4646644@192.168.10.20:5080;transport=udp callee_cseq::0 callee_route_set::

结果应如下所示。

state::4 callee_contact::sip:4646644@192.168.10.10:5080;transport=udp state::2 callee_contact::sip:4646644@192.168.10.20:5080;transport=udp

非常感谢任何帮助。谢谢。
