匹配的正则表达式

1.<tag>[\s\S]*?</tag>

把表达式中的tag替换成对就的html元素即可

以下是HTML内容

正则表达式到底是什么东西？

在编写处理字符串的程序或网页时，经常会有查找符合某些复杂规则的字符串的需要。正则表达式就是用于描述这些规则的工具。换句话说，正则表达式就是记录文本规则的代码。
常用元字符
代码说明.匹配除换行符以外的任意字符\w匹配字母或数字或下划线或汉字\s匹配任意的空白符\d匹配数字\b匹配单词的开始或结束^匹配字符串的开始$匹配字符串的结束
常用限定符
代码/语法说明*重复零次或更多次+重复一次或更多次?重复零次或一次{n}重复n次{n,}重复n次或更多次{n,m}重复n到m次
常用反义词
代码/语法说明\W匹配任意不是字母，数字，下划线，汉字的字符\S匹配任意不是空白符的字符\D匹配任意非数字的字符\B匹配不是单词开头或结束的位置[^x]匹配除了x以外的任意字符[^aeiou]匹配除了aeiou这几个字母以外的任意字符
