正则表达式匹配字符串，其中单词后跟空格，然后是数字点或连字符，单词后跟空格，然后（一些信息）

Question

我有一个具有以下格式的字符串： name category (more info)

例如： Foo Bar-8.io 5.61.0-rc-1 (data)

我需要一个正则表达式，它基本上过滤掉符合上述格式的字符串。

名称可以是带有空格的字母数字， -和.

类别可以以数字开头，后跟单词，包括点或连字符

数据可以是任何包含在()中的.*

我试过这个： ^[\w\s]+.*\s.*\(.*\)$但似乎没有涵盖上述模式。

Answer 1

利用

^(.*)\s+(\S+)\s+\((.*)\)$

请参阅正则表达式证明。
