麻烦大家帮忙看看这个代码，要处理的字符串是：
He_Chi10_MX2-1 Abis TP 53[_53];major (2);communicationsAlarm;X721-lossOfFrame;190342 BSC-TRANS [101] LFA [2];();();((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=101002 190342));1;unAcknowledged (0);cleared (1);20120613031312.0Z;;1.3.12.2.1006.53.1.2.0.3.1014;0.0.13.3100.0.7.68#9/0.0.13.3100.0.7.20#1/0.0.13.3100.0.7.48#53;20120613092957.0Z;manualPurge (3);1;
正则表达式是：[[:alnum:]*-_ \[\]]*;
匹配的结果却为：20120613031311.4Z

想要的结果是：He_Chi10_MX2-1 Abis TP 53[_53];
请大家帮忙看看是哪里出的问题，谢谢大家了
