With the(?i)syntax, the regular expression is case insensitive. The(es)?indicates that "es" characters might be included zero times or once. found := re.FindAllString(content, -1) We look for all occurrences of the defined regular expression withFindAllString. The second parameter is the...
确切地说是兼容RE2语法。相关资料:http://code.google.com/p/re2/wiki/Syntax,包:regexp/syntax 注意:regexp包的正则表达式实现保证运行时间随着输入大小线性增长的(即复杂度为 O(n),其中 n 为输入的长度),这一点,很多正则表达式的开源实现无法保证,参见:RSC 的《Regular Expression Matching Can Be Simple A...
fmt.Printf("%v", r.MatchString("Hello Regular Expression.")) 1. 2. 3. CompilePOSIX/MustCompilePOSIX CompilePOSIX和MustCompilePOSIX方法运行着的是一个略为不同的引擎。这两个里面采用的是 POSIX ERE (extended regular expression) 引擎。从 Go 语言的视角看它们采用了严格的规则集合,也就是egrep所支持的...
// Compile parses a regular expression and returns, if successful, // a Regexp object that can be used to match against text. //... // For POSIX leftmost-longest matching, see CompilePOSIX. func Compile(expr string) (*Regexp, error) { return compile(expr, syntax.Perl, false) } /...
Go 语言通过 regexp(regular expression)标准包为正则表达式提供了官方支持,如果你已经使用过其他编程语言提供的正则相关功能,那么你应该对 Go 语言版本的不会太陌生。但是它们之间也有一些小的差异,因为 Go 实现的是 RE2 标准,详细的语法描述可参考:code.google.com/p/re2/wiki/Syntax 如遇...

Anyway, you can still use the raw regular expressions syntax in combination with helpers. rex.New( rex.Chars.Begin(), rex.Group.Define( // `Raw` can be placed anywhere in blocks. rex.Common.Raw(`[a-z]+\d+[A-Z]*`), ), rex.Chars.End(), ) Or just raw regular expression with ...
