    <a href="http://127.0.0.1/<b>test1</b>"><b>test</b></a></br><a href="http://127.0.0.1/<b>test2</b><b>test2</b>"><b>test2</b></a></br><a href="http://127.0.0.1/<b>test3</b><b>test3</b><b>test3</b>">test3</a></br><b>thisistest1</b><b>thisistest2</b>


    如上 html 示例代码,想用正则替换掉<a href="http://127.0.0.1/<b>test1</b>"> 这种格式里面的<b>和</b>标签,用 re.sub,总是有点问题,要么删除的不干净,要么过了,把后面标签外的也去掉了.请大家帮忙看看,谢谢了!

    基本算解决了吧,先把 br 换成 /n ,之前正则总是误伤,
    这样,非贪婪匹配的时候就不会跨行误伤
