以下python正则表达式：

    <!-- DW6 --><!-- kelly 10-28-16 the white box welcome email -->

conditional_search = r"(<!--.*\[if.*\]>.*<!--.*\n*.*endif\]-->)" it = re.finditer(conditional_search, html, flags=re.DOTALL) print([tuple(i.groups()) for i in it]) 的输出匹配从print到<!-- DW6 -->标记末尾的所有内容。我只是想找到每个</style> HTML评论块（包括双<!--if）。

答案 0 :(得分：1)

给它一个机会。基本上我只是撕掉所有的回车（也许你想保留它们？）并调整正则表达式。如果正则表达式不清楚，请留下评论，我认为它非常直接。如果我理解你在寻找什么，这应该可以解决问题。这是我的整个测试脚本：
