Question

我想匹配一个单词＆＃34; some＆＃34; in＆＃34;我想要一些有些馅饼＆＃34;并替换任何字符串匹配它与{..}的串联，所以它的输出应该是＆＃34;我想要{somesomesome}馅饼＆＃34;但我的是＃34;我想要{有些}馅饼＆＃34;。

这是我的正则表达式：

（一些）*一些

Answer 1

以下一个样本：

    String some = "some";
    String input = "i want somesomesome pies, and some apples, and somesomesomesome pears";
    // at least one 'some' word
    System.out.println(input.replaceAll("((?:"+some+")+)", "{$1}"));
    // at least two 'some' word
    System.out.println(input.replaceAll("((?:"+some+"){2,})", "{$1}"));

输出结果为：

i want {somesomesome} pies, and {some} apples, and {somesomesomesome} pears
i want {somesomesome} pies, and some apples, and {somesomesomesome} pears
