比如这样一段字符串
<meta name="detectify-verification" content="d0264f228155c7a1f72c3d91c17ce8fb" />
<meta name="p:domain_verify" content="b87e3b55b409494aab88c1610b05a5f0"/>
<meta name="alexaVerifyID" content="OFc8dmwZo7ttU4UCnDh1rKDtLlY" />
<meta name="baidu-site-verification" content="D00WizvYyr" />

content 里面的内容是随机的，如何把他们替换成
<meta name="detectify-verification" content="d0264f228155c7a1f72c3d91c17ce8fb.html" />
<meta name="p:domain_verify" content="b87e3b55b409494aab88c1610b05a5f0.html"/>
<meta name="alexaVerifyID" content="OFc8dmwZo7ttU4UCnDh1rKDtLlY.html" />
<meta name="baidu-site-verification" content="D00WizvYyr.html" />

我只懂得把 content 的内容提取出来，再 for 循环一个个替换，但是感觉有点麻烦，有没有办法不使用循环，直接用 replace 或者 re 搞定？

不就把
" />
替换成
.html" />
?

你不会从来没用过替换方法吧？

不是，感觉我问的方式有问题，这种问法的确一替换就好了，我再想想怎么问好
