java - 相似但不相同的字符串序列

Question

如何匹配如下序列:

You wound DUMMY TARGET for 100 points of damage

但不是:

You wound DUMMY TARGET with SKILL for 100 points of damage

使用正则表达式:

^You wound ([\\w\\s]+)(?!with) for (\\d+) points of damage

上面的正则表达式匹配两个字符串，而我希望只匹配第一个。有什么方法可以使它起作用吗？

示例 Java 代码:

import java.util.regex.*;

public class Dummy {

 static Pattern pattern = Pattern.compile("^You wound ([\\w\\s]+)(?!with) for (\\d+) points of damage");
 static Matcher matcher = pattern.matcher("");
 static String FIRST_SEQUENCE =  "You wound DUMMY TARGET for 100 points of damage";
 static String SECOND_SEQUENCE =  "You wound DUMMY TARGET with SKILL for 100 points of damage";

 public static void main(String...args) {  
  if (matcher.reset(FIRST_SEQUENCE).matches())
   System.out.println("First match. Ok!");

  if (matcher.reset(SECOND_SEQUENCE).matches())
   System.out.println("Second match. Wrong!");
 }
}

Answer 1

尝试使用非贪婪运算符 +? , ([\\w\\s]+?)

^You wound ([\\w\\s]+?)(?!with) for (\\d+) points of damage
