Do you know regular expressions? If so, the below should hopefully make sense. If not, try it and see if it works, and if there are different format strings that need to be catered for, I can modify it for you.

package ee.yvanVallee;

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

public class ExtractFields {
    
    public static void main(String[] args) {
        String testString = "tn='447795584165' ptr {id=0}";
        
        
        
        Pattern pattern = Pattern.compile("tn='([^']*)' ptr \\{id=([^}]*)\\}");
        
        Matcher matcher = pattern.matcher(testString);
        if (matcher.matches() && matcher.groupCount() >= 2) {
            String tn = matcher.group(1);
            String id = matcher.group(2);
            
            
            System.out.println("tn: " + tn);
            System.out.println("id: " + id);
        }
    }
    
}

Or if the values of both tn and id are always numeric (longs) only, you could do this...

package ee.yvanVallee;

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

public class ExtractFields {
    
    public static void main(String[] args) {
        String testString = "tn='447795584165' ptr {id=0}";
        
        
        
        Pattern pattern = Pattern.compile("tn='(\\d*)' ptr \\{id=(\\d*)\\}");
        
        Matcher matcher = pattern.matcher(testString);
        if (matcher.matches() && matcher.groupCount() >= 2) {
            long tn = new Long(matcher.group(1));
            long id = new Long(matcher.group(2));
            
            
            System.out.println("tn: " + tn);
            System.out.println("id: " + id);
        }
    }
    
}
