测试字符串：
<style>v\:*{
BEHAVIOR:url(#default#VML)
}o\:*

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>
varresult=testData.replace(<style(([\s\S])*?)<\/style>,'');
2.会替换所有testData中所有的<style>标签
varresult=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。
