perl regex 捕获重复组 [英] perl regex to capture repeating group

问题描述

我想要一个正则表达式，它匹配一行开头的某些内容，然后匹配(并返回)所有其他单词.例如，给定这一行:

I want a regular expression that matches something at the beginning of a line, and then matches (and returns) all other words. For instance, given this line:

$line = "one two three etc";

我想要这样的东西(不起作用):

I want something like this (that doesn't work):

@matches= $line=~ /^one(?:\s+(\S+))$/;

返回到@matches，单词二"、三"、等".

to return into @matches, the words "two", "three", "etc".

我不想知道如何得到这些词.我想用正则表达式来做.看起来很简单，但我一直没能想出解决方案.

I don't want to know how to get the words. I want to do it with a regular expression. It seems so simple, but I have not been able to come with a solution.
