包括三种方式:匹配(regex_match)、查找(regex_search)、替换(regex_replace)。 匹配很简单,直接将待匹配字符串和模式字符串传入到regex_match中,返回一个bool量来指明待匹配的字符串是否满足模式字符串的规则。匹配整个str字符串。 bool match = regex_match(str, e); // 匹配整个字符串str 1. 2. 查找是在整...

The substring \n here is the newline character. To fully understand this example, you'll first need to learn about JavaScript Regex Quantifiers. The first expression /.+/g without the s flag will match every single line in str. The highlighted portions shown below represent the matches: "Co...
If there are newline symbols inside, you will need to use lazy matching with [\s\S] or [^] in JS. See Lazy Quantifier Solution at rexegg.com for more details about lazy dot matching. Here is a sample regex: /\burl\((.*?)\)/gi See demo Here, we match url( (as a whole w...
