java - 用 RegEx 替换 2 个单词之间最后出现的单词

Question

我正在 Java 上使用 RegEx，这就是我遇到的问题。

我有一个简单的字符串，例如

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

我必须找到每个子字符串，直到两个 ORDER 之间最后一次出现 ASC 为止，并将它们替换为单词 QQQ。

以下是一些示例:

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

试试这个

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