正则表达式匹配带括号的复杂表达式样例
在项⽬中，遇到需求，需要进⾏规则⼊库，想到使⽤正则进⾏表达式的拆分和分类，具体如下：
Operation Mode(Operation Mode_2) (Approve CR1) equals Accept And ( Need Physical Access(Need Physical Access) (Create CR)
does not equal Switch Site Or ( Need Physical Access(Need Physical Access) (Create CR) equals Switch Site And Region(Region)

⽬标是：拆分介于表⽰逻辑运算的“And”或者“Or”的⼦句，⽐如：Operation Mode(Operation Mode_2) (Approve CR1) equals Accept；Need Physical Access(Need Physical Access) (Create CR) does not equal Switch Site等⼦句，以便于后续的处理；
tickets 正则表达式的思路：上述字符串的⼦句是“Operation Mode”等诸如此类的关键字+括号+括号+equals等表⽰所属关系的关键字+各类单项，
那么，
坠落星辰第一季
1.⾸先整理出来，⽤于匹配开头的关键字的⼦句，记作K1：(Operation Mode|Need Physical Access|Change Type|Region)
2.接下来是整理出匹配equals等表⽰所属关系的关键字，记作K2：( belongs to | equals | contains | does not equal | does not contain | does not belong to )
3.接下来是整理出匹配两个连续括号部分的第⼀个括号，记作S1，这⾥有这么⼏类：（字符串+空格+字符串）
那么对应的S1为：((\((\w* ?\w*)*\))|(\((\w*_\w*)*\))) ：其中(\w* ?\w*)⽤于匹配（字符串+空格+字符串）（单个字符串）这两种格式，(\w* ?\w*)*⽤于匹配上述两种格式的多个字符串，如：(Need Physical Access) 。其中(\w*_\w*)*⽤于匹配（字符串_字符串）的这种情况；
4.接下来是整理出匹配两个连续括号部分的第⼆个括号，记作S2，这⾥仅有⼀类：（字符串+空格+字符串）
那么对应的S2为：这地⽅第⼆个括号的情况包含于第⼀类，所以令S2=S1
overfly 5.接下来，接下来需要取出表⽰所属关系的字符串后边的字段，这⾥有如下情况，在所属关系的字符串后边的字段中，有 “字符串空格And（”或者“字符串+Or（ ”或者“And”或者“Or”，那么，可以使⽤
不包含字段：((?!所要剔除的字符串).)*，但是，这个地⽅需要注意的是，有些关系运算符后边的字符串也包含And或者Or，那么，我们需要进⾏如下处理，需要提出的只是And或者Or后边是K1匹配出来的⼦串，S3表达式如下：
S3：((?!( And \(|Or \(| \)| And (K1S1 S1)| Or (K1S1 S1))).)*
那么，最终的表达式如下所⽰K1S1 S2 K2 S3，
即：(Operation Mode|Need Physical Access|Change Type|Region)((\((\w* ?\w*)*\))|(\((\w*_\w*)*\))) ((\((\w* ?\w*)*\))|(\((\w*_\w*)*\)))( belongs to | equals | contains | does not equal | does not contain | does not belong to )((?!( And \(|Or \(| \)| And ((Operation Mode|Need Physical Access|Change Type|Region) ((\((\w* ?\w*)*\))|(\((\w*_\w*)*\))) ((\((\w* ?\w*)*\))|(\((\w*_\w*)*\))))| Or ((Operation Mode|Need Physical Access|Change Type|Region)((\((\w* ?\w*)*\))|(\ ((\w*_\w*)*\))) ((\((\w* ?\w*)*\))|(\((\w*_\w*)*\)))))).)*
匹配的效果如下所⽰：
