正则表达式，用于匹配空格或标点和非字母数字

Question

我有这个正则表达式：

(\s+)|([.,!?:;'\"\'-])

这与数组中的任何空格或标点匹配，但并非与所有标点匹配，因此我正在努力寻找与任何标点匹配的示例。

我考虑过匹配字符不是字母数字的地方，但这会导致带有重音字母和不同词典的问题。

标点符号是否包含所有内容，例如（当我说我希望包含符号的标点符号时）：

  

`，。＃@

等

Answer 1

您可以使用[\p{P}\p{S}]：

(\s+)|([\p{P}\p{S}])

[\p{P}\p{S}]将匹配标点符号或字符char的任何字符。

Answer 2

如果不需要匹配下划线，则可以使用

  

\ W

与其匹配的不是数字，字母或下划线。
