Question

我正在使用java并且有一个类似I am going to manchester的模式我想使用正则表达式来匹配所有类型为I am going（某些字符串）to manchester的句子。所以我的字符串i am going to manchester也会匹配I am going with my family to manchester

有谁知道正则表达式实现这一目标？

我尝试了以下但不起作用：

Pattern.compile("i am going (\\w+) to mancheter")

我正在使用Pattern和Matcher。

Answer 1

试一试：

输入：

I am going with my family to manchester potato

输出：

I am going with my family to manchester

Java代码：

import java.util.regex.Matcher;
import java.util.regex.Pattern;

// one class needs to have a main() method
public class HelloWorld {
 // arguments are passed using the text field below this editor
 public static void main(String[] args) {

  final String regex = "(<?I am going)(.+)(?>manchester)";
  final String string = "I am going with my family to manchester patata";

  final Pattern pattern = Pattern.compile(regex);
  final Matcher matcher = pattern.matcher(string);
  String answer = "";

  while (matcher.find()) {
   answer = matcher.group(0) + "";
  }


  System.out.println(answer);
 }
}

使用正则表达式忽略子字符串
