第一次尝试：<style[^>/]*>(.*?)</style> 发现有换行的情况匹配不了，因为.是匹配除了换行符（/n）以外的任意一个字符。
第二次尝试：<style(([\s\S])*?)</style> 成功
匹配<div>只需要把<style>换成<div>即可
1. 只替换匹配到的第一个<style>
var result= testData.replace(<style(([\s\S])*?)<\/style>, '');
2. 会替换所有testData中所有的<style>标签
var result= testData.replace(/<style(([\s\S])*?)<\/style>/g, '');
g：代表可以进行全局匹配。
i：代表不区分大小写匹配。
m：代表可以进行多行匹配。
以上内容是小编给大家介绍的JavaScript正则表达式匹配<div><style>标签，希望对大家有所帮助！
