c# - 正则表达式在模式后匹配句子中的单词

Question

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

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

但它只fish作为第二组返回。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，如果您想在每次捕获中匹配除一个单词之外的所有单词：

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.
}

祝你的任务好运。
