各路神仙，给我指点一二吧，C++字符串处理问题
有这样一个字符串：
20120702172341.0Z;HeChi1_MX3-1 Abis TP 58[_1-3,6,1];minor (3);communicationsAlarm;M3100-farEndReceiverFailure;BSC-TRANS [101] RAI [5],181454;();();((Alcatel Additional Information,significant, Additional Information is ),(Alcatel Additional Information,significant,-- OMC3 ALARM --),(urlAddressOnAlarmDictionary,significant,https://gxsesn045:7443helpd/cgi-bin/alarm_search.cgi?specific_problem=181454,101005));1;unAcknowledged (0);cleared (1);20120702172341.2Z;;1.3.12.2.1006.53.1.2.0.3.1014;0.0.13.3100.0.7.68#14/0.0.13.3100.0.7.20#1/0.0.13.3100.0.7.48#58;1;
现在需要用分号把Chi1_MX3-1 Abis TP 58[_1-3,6,1];给匹配出来。请哪位帮我写一个完整的程序出来，要求程序不能出现任何空指针等一系列任何异常，非常非常感谢

这叫神马需求, 第一个分号和第二个分号之间不就是嘛.
