RegEx带来更多乐趣.... [英] Further Fun with RegEx....

问题描述

大家好，
这与昨天询问的有关使用RegEx为其赋予完整标题的问题有关:
正则表达式的疯狂，或如何使其可变?
通过使用ProEggNog的答案，我设法使应用程序使用

 // 字符串regExp = @(?< =<).+? (?=>)； //在RegEx中使用< >围绕数据
     // 字符串regExp = @(?< = \ [).+?(?= \])" ;; //针对数据的[]使用RegEx 
     // 字符串regExp = @(?< =！).+?(?=！)";//正则表达式工作！ ！围绕数据
          字符串 regExp =  @" ).+?(?= \ " ;  ?????????  

但是我试图在数据周围使用"，尽管我的第一个操作是将\放在前面"，因为智能感知表明这是该语句的结尾"，这是30分钟RegEx的Expresso应用程序教程似乎与我同意吗?任何人都除了不要使用"???

解决方案

对，是的...
试试:

 字符串 regExp =  @" (?< = \").+?(?= \")"; 

在为字符串加上"@"前缀时，将变为普通的黑斜线处理
关闭，因此\不再起作用.您需要使用"代替插入单引号，并在其自身上加上反斜杠以插入反斜杠.

Hi All,
This is related to a question asked yesterday about the use of RegEx to give it full title:
RegEx madness, or how to make it variable?
by using ProEggNog''s answers I have managed to get the application to use

//     string regExp = @"(?<=<).+?(?=>)";     //working RegEx for < > around data
     //     string regExp = @"(?<=\[).+?(?=\])";//working RegEx for [ ] around data
     //     string regExp = @"(?<=!).+?(?=!)";//working RegEx for ! ! around data
          string regExp = @"(?<=\").+?(?=\")";//?????????

however I''m trying use " around the data my first though was to place \ in front of the " as the intelli-sense showed it was seeing the " as the closing " for the statement, the Expresso app for the 30 Minute RegEx tutorial seems to agree with me though? anyone any ideas apart from don''t use " ???

解决方案

Right, yes...
Try:

string regExp = @"(?<=\"").+?(?=\"")";

When you prefix a string with ''@'' it turns normal blackslash processing
off, so \" doesn''t work any more. You need to use "" instead to insert a single double quote, and backslash on it''s own to insert a backslash.
