Problem with REGEXP_SUBSTR related query.

Question

I am having a problem with this query:
SELECT *
  FROM (    SELECT REGEXP_SUBSTR ('{SUMMER}|{POINT OF SALE}',
                                           '({)([A-Z]+ *[A-Z]*)(})',
                                           1,
                                           LEVEL,
                                           'i',
                                           2)
                               val
              FROM DUAL
        CONNECT BY LEVEL <=
                      REGEXP_COUNT ('{SUMMER}|{POINT OF SALE}', '|') + 1)
WHERE val IS NOT NULL
I need the output in 2 rows in this format:
VAL
====
SUMMER
POINT OF SALE
But I am not able to get 'POINT OF SALE' in the output because of the blank space, or maybe some other reason. Can anyone correct my query?
