使用正则表达式忽略子字符串

Question

我正在使用Java并有一个模式，就像I am going to manchester我想使用正则表达式来匹配这将匹配I am going to manchester类型（某些字符串）的所有句子。 所以我i am going to manchester琴弦也要和I am going with my family to manchester琴弦相匹配

有谁知道正则表达式来实现这一目标？

我尝试了以下操作，但不起作用：

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

我正在使用Pattern和Matcher 。

Answer 1

试试吧：

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);
 }
}
