JavaScript正则表达式匹配 div style标签

测试字符串：

<style>v\:* { 
BEHAVIOR: url(#default#VML) 
} o\:* 
{ 
BEHAVIOR: url(#default#VML) 
} w\:*
{ 
BEHAVIOR: url(#default#VML) 
} 
.shape 
{ 
BEHAVIOR: url(#default#VML) 
}
</style>

</style>

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。
