正則表達式在模式后匹配句子中的單詞

Question

我想捕捉小組fish egg chicken beef在句子中How much is fish egg chicken beef ? 。 我嘗試過

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

但它僅是第二組返回的fish 。 我在這里做錯了什么？

Answer 1

也許正則表達式應該是：

How much is (.*)\?

或者，如果您想匹配每個捕獲中除一個單詞以外的所有單詞：

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.
}

祝您一切順利。
