首先简单介绍一下正则表达式的基本写法及用法

\d 匹配任何一个数字，即[0-9]

\d+表示1个以上的数字

\d*标示0个或多个数字

\s 表示分隔符，包括空格、制表符和换行符

\s* 0个或多个分隔符

\w 表示字母、数字和下划线，这里还包括Unicode字符，不同的语言里有些不同

\w{4} 表示4个非空白字符

. 表示任何一个字符，不包括换行符

.* 表示任何多个字符，当然也不包括换行符了

^([0-9]) 表示数字开头

([0-9])$ 表示数字结尾

([0-9A-Za-z]) 表示数字字母

| 表示或的关系，如\d|\w 表示数字或字母

(.|[\r\n])* 表示任何多个字符，包括换行符，贪婪扫描

(.|[\r\n])*? 表示任何多个字符，包括换行符，懒惰扫描

(?:.|[\\r\\n]) 以(?:开头时的分组信息，表示不读取到缓冲器里，避免rangeAtIndex调用时产生副作用，后面还会遇到这样的(?:写法
