我有一个文件包含如下数据...
/tutordashboard/manageTutorLogInStatus/?ua=TQ-AUTOCLOSE-REENTER&filterId=089089087087080&dt=1325757272
/tutordashboard/manageTutorLogInStatus/?ua=TQ-AUTOCLOSE-REENTER&filterId=089089087087080&dt=1873982869
/tutordashboard/manageTutorLogInStatus/?ua=TQ-BUTTON-DISABLED&sessionType=1&sessionId=4938718&filterId=97462&dt=1354822214604
/tutordashboard/manageTutorLogInStatus/?ua=TQ-BUTTON-DISABLED&sessionType=1&sessionId=4951063&filterId=95997&dt=1354807593071
/tutordashboard/manageTutorLogInStatus/?ua=TQ-BUTTON-DISABLED&sessionType=2&sessionId=4957338&filterId=99353&dt=1354752909284
如何获得在每行中打印到第三次出现“/”的输出？
