用RegEx替換2個單詞之間最后出現的單詞

Question

我正在使用Java上的RegEx，這就是我要堅持的地方。

我有一個簡單的字符串

String sample1 = "word 231 sadas aslkjasf anything ORDER what whut ASC hello ORDER whatever."

我必須找到每個子字符串，直到兩個ORDER之間最后一次出現ASC為止，並用單詞QQQ替換它們。

這里有些例子：

String sample1 = "word 231 sadas aslkjasf anything ORDER what whut ASC hello ORDER whatever.";
String result1 = "word 231 sadas aslkjasf anything QQQ hello ORDER whatever.";
// replaced "ORDER what whut ASC"

String sample2 = "word 111 sadas anything ORDER what whut yeap ASC nope ASC maybe ORDER yeah.";
String result2 = "word 111 sadas anything QQQ maybe ORDER yeah.";
// replaced "ORDER what whut yeap ASC nope ASC"

Answer 1

嘗試這個

    s = s.replaceAll("(ORDER.*ASC)(?=.*?ORDER.*)", "QQQ");
