※ 引述《chrisdar (克里斯)》之铭言： : 现在我有一系列单选题问卷如下 : (Q1) Question 1 : (1)[ ] Answer 1 for Question 1 : (2)[ ] Answer 2 for Question 1 : (3)[*] Answer 3 for Question 1 : (4)[ ] Answer 4 for Question 1 : (Q2) Question 2 : (1)[ ] Answer 1 for Question 2 : (2)[ ] Answer 2 for Question 2 : (3)[ ] Answer 3 for Question 2 : (4)[ ] Answer 4 for Question 2 : (Q3) Question 3 : (1)[*] Answer 1 for Question 3 : (2)[ ] Answer 2 for Question 3 : (3)[*] Answer 3 for Question 3 : (4)[ ] Answer 4 for Question 3 : (Q4) Question 4 : (1)[*] Answer 1 for Question 4 : (2)[ ] Answer 2 for Question 4 : (3)[ ] Answer 3 for Question 4 : (4)[ ] Answer 4 for Question 4 : Pattern : \(Q(\d+)\).*?\((\d+)\)\[\*\] : 现在问题出在 : 1. Q2 因为没有作答 导致把 Q3 的答案带到 Q2 去 : 2. Q3 重复作答也无法排除 : 可否提供一些思考方式或做法 谢谢 分成两次来作比较轻松: 第一步: 将每个 Question 切割成单独的区块 \(Q\d+\)[\s\w]+(\(\d+\)\[[\s*]\][\s\w]+)+ 或 (?<=\(Q\d+\))(.*?)(?=\(Q\d+\)) 第二步: 对每个区块个别进行搜寻 \(\d+\)\[\*\][\s\w]+ 当然，使用 regexp 常常会有一种冲动想一次解决 :P -- http://godspeedlee.myweb.hinet.net/ --
