I am trying to match and get the last occurrence of a pattern in my file using notepad++.My text:X12Source =asdjkasjd file="x/y1.dun" "x/y2.dun" "x/y3.dun"asds12 X22 p/q/xy.dunasda=23source =asdf X4410001001 file="abc.dun"What I expect using find-and-replace is this:X12 x/y3.dunX22 p/q/xy.dunX44 abc.dunWhat I have tried so far:(X\d{2}).*?([^"\s]+dun)((?!X\d{2}).)*replace with:$1\t\t$2\nBut it returns me this:X12 x/y1.dun //Which is the first matchX22 p/q/xy.dunX44 abc.dunHow do I get the last match inside a match? I am looking for a general way for getting the last match. 解决方案 You may match and capture what you need to keep and just match what you do not need, and only replace with text when a capture group is matched:Find What: (?s)\b(X\d{2})(?:(?!X\d{2}).)*["\s]([^"\s]+\.dun)|(?:(?!X\d{2}).)*Replace With: (?{1}$1\t\t$2\n)See the regex pattern demo.Details:(?s) - a DOTALL modifier (you may remove it and check the . matches newline option)\b - a leading word boundary to match X at the start of a word(X\d{2}) - Group 1 capturing a X (note that Match Case must be turned on if you do not want to match a lowercase x) and any two digits(?:(?!X\d{2}).)* - a tempered greedy token matching any char, zero or more repetitions, that is not followed with X and any two digits. Since it is greedy, it will make it up to the location where the next character starts the forbidden sequence and will backtrack to the last "dun" required by the subsequent subpattern.["\s] - a whitespace or a double quote([^"\s]+\.dun) - Group 2 capturing one or more chars other than whitespace and double quote, then a dot and a dun substring| - or(?:(?!X\d{2}).)* - the same tempered greedy token as above.Replacement details:(?{1} - if Group 1 matched....$1\t\t$2\n - replace with the first group value, two tabs, the second group value and a newline) - else replace with an empty string. 这篇关于从多个比赛中获取最后一场比赛的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
