: Pattern : \(Q(\d+)\).*?\((\d+)\)\[\*\]
: 現在問題出在
: 1. Q2 因為沒有作答 導致把 Q3 的答案帶到 Q2 去
: 2. Q3 重複作答也無法排除
: 可否提供一些思考方式或做法 謝謝
分成兩次來作比較輕鬆:
第一步: 將每個 Question 切割成單獨的區塊
\(Q\d+\)[\s\w]+(\(\d+\)\[[\s*]\][\s\w]+)+
或
(?<=\(Q\d+\))(.*?)(?=\(Q\d+\))
第二步: 對每個區塊個別進行搜尋
\(\d+\)\[\*\][\s\w]+
當然，使用 regexp 常常會有一種衝動想一次解決 :P
