求js用正则把段落p和diy把替换为换行br

[fmwind]

求js,要求把复制html过来内容中的<p></p>和<div></div>转换成br标签，同时去掉页面中除了br标签以外的的其它标签了。

直接做几次替换吧，写正则好烦的啊

var str = `
<p>gggggg<img src="testing.jpg" />ffff</p>
<div id="box">xxx <span class="test">1234</span>  xx</div>
`;
str = str.replace(/<\/(p|div)>/ig,"<br />").replace(/<(?!br\b)\/?\w+[^>]*>/ig,"");
alert(str);

写正则表达式

？{4,5,6,7}; //maybe, this will be more easy; {0,1,2,3} is great, but heavy and expensive.
