Answer 1

How about this:

PROCEDURE xmltest IS
  v_userlist XMLType;
  v_count NUMBER(38) := 1;
BEGIN
  /* define XML variable */
  v_userlist := XMLType('
    
        
            user1
        
        
            user2
        
        
            user3
        
    ');

  /* for each user, print out their name (each element can be extracted using xpath '//user[1]' '//user[2]' etc) */
  WHILE v_userlist.existsNode('//user[' || v_count || ']') = 1 LOOP
    dbms_output.put_line(v_userlist.extract('//user[' || v_count || ']/name/text()').getStringVal());
    v_count := v_count + 1;
  END LOOP;
END;
