    My code passed all test case

    import java.io.*;
import java.util.*;
import java.util.regex.*;

public class Solution {

    public static void main(String[] args) {
        /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
        Pattern p = Pattern.compile("<(.+)>([^<]+)</\\1>");
        
        Scanner input = new Scanner(System.in);
        int n = Integer.parseInt(input.nextLine());
        
        while(n-- > 0){
            String textStr = input.nextLine();
            Matcher m = p.matcher(textStr);
            boolean found = false;
            
            while(m.find()){
                System.out.println(m.group(2));
                found =true;
            }
            if(!found){
                System.out.println("None");
            }
        }
    }
}

    Interesting problem! It’s a good exercise in parsing and understanding how tag-based languages like XML and HTML work, especially handling matching tags and nested content. Playexchange Login

    My solution works, which I had to look up, since the tests seemed to be flawed.
