正则表达式在Java中提取标签值对

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

public class RegexExample {
    public static void main(String[] args) {
        String input = "<tag1>value1</tag1><tag2>value2</tag2>";
        Pattern pattern = Pattern.compile("<(\\w+)>([^<]+)</\\1>");
        Matcher matcher = pattern.matcher(input);
        while (matcher.find()) {
            System.out.println("Tag: " + matcher.group(1));
            System.out.println("Value: " + matcher.group(2));
        }
    }
}
