I'm trying to use a Regex expression I've found in this website and it doesn't seem to work. Any ideas?
我正在尝试使用我在本网站上找到的正则表达式，它似乎不起作用。有任何想法吗？
Input string:
输入字符串：
sFetch = "123<script type=\"text/javascript\">\n\t\tfunction utmx_section(){}function utmx(){}\n\t\t(function()})();\n\t</script>456";
Regex:
正则表达式：
sFetch = Regex.Replace(sFetch, "<script.*?>.*?</script>", "", RegexOptions.IgnoreCase);

Add RegexOptions.Singleline
添加RegexOptions.Singleline
RegexOptions.IgnoreCase | RegexOptions.Singleline
And that will never work on follow one.
这将永远不会影响到一个。
<script

alert(1)
</script

The reason the regex fails is that your input has newlines and the meta char . does not match it.
正则表达式失败的原因是你的输入有换行符和元字符。与它不符。
To solve this you can use the RegexOptions.Singleline option as S.Mark says, or you can change the regex to:
要解决此问题，您可以使用RegexOptions.Singleline选项作为S.Mark说，或者您可以将正则表达式更改为：
"<script[\d\D]*?>[\d\D]*?</script>"
which used [\d\D] instead of ..
用[\ d \ D]代替..
\d is any digit and \D is any non-digit, so [\d\D] is a digit or a non-digit which is effectively any char.
\ d是任何数字，\ D是任何非数字，因此[\ d \ D]是一个数字或非数字，实际上是任何字符。

If you actually want to sanitize a html string (and you're using .NET) then take a look at the Microsoft Web Protection Library:
如果您确实想要清理html字符串（并且您使用的是.NET），那么请查看Microsoft Web Protection Library：
Sanitizer.GetSafeHtmlFragment(untrustedHtml);

This is a bit shorter:
这有点短：
"<script[^<]*</script>"
or
要么
"<[^>]*>[^>]*>"
