正则表达式匹配句子后的单词

Question

我想在句子How much is fish egg chicken beef ?中捕获组fish egg chicken beef。我试过

how much is ((?>\w+))* \\? 

但是它的唯一返回fish作为第二组。我在这里做错了什么？

Answer 1

也许正则表达式应该是：

How much is (.*)\? 

或者，如果你想匹配在每个捕获所有的话，只有一个词：

How much is (?:(\w+)\s*)+\? 

Regex regexWords = new Regex(@"How much is (?:(\w+)\s*)+\?"); 

foreach(Capture word in regexWords.Match(input).Groups[1].Captures) 
{ 
    // word.Value contains one word. 
} 

祝你好运与你的追求。
