我正在尝试使用正则表达式匹配< >之间的所有文本，包括换行符和回车符。
(<.*>)|(<.*\n)
我正在测试的Regex101字符串位于：https://regex101.com/r/wuFeG9/1
正如您所看到的，它匹配< >之间的所有文本情况，除非中间有回车符/换行符 - 组2的红色高亮显示其中断的位置。
当我在< >括号内有换行符/回车符时，我就会失败。我无法让\s与之匹配，即使notepad ++中的文字显示那里有回车符。
任何帮助将不胜感激!!
提前谢谢。

您可以使用
<[^>]*>
此处[^>]表示“>以外的任何字符”。这是一个角色类。
请注意，如果要解析HTML，而不是盲目搜索和替换，则regex不是一个好方法。此外，正则表达式无法干净地处理损坏的HTML。请参阅How do you parse and process HTML/XML in PHP?了解正确的方法。
