SDO_UTIL.FROM_WKBGEOMETRY function

Question

Hi there.
I have been struggling to convert WKB(Blobs) to SDO_GEOMETRY.
If I understand correctly there is some SDO functions that doesn't`t work in Oracle XE or should I rather say it has a differant syntax in XE than enterprise.
My problem is that I want to transform WKR(Blobs) to SDO_Geometry.
I tried the following procedure but to no avail.
CREATE OR REPLACE PROCEDURE IMIS_MAP_GEO.BLOB_TO_SDO
IS
CURSOR TCURS IS
SELECT SEQ,
SDO_GEOM.VALIDATE_GEOMETRY(SDO_UTIL.SIMPLIFY((SDO_UTIL.FROM_WKBGEOMETRY(A.GEOMETRY)),0.00000005),0.000001) AS "VALIDATION",
SDO_UTIL.SIMPLIFY((SDO_UTIL.FROM_WKBGEOMETRY(A.GEOMETRY)),0.00000005) AS GEOM
FROM LAND_PARCELS_REGD_ERVEN A
WHERE GEOMETRY IS NOT NULL;
BEGIN
FOR TROW IN TCURS LOOP
IF TROW."VALIDATION" = 'TRUE'
THEN
UPDATE LAND_PARCELS_REGD_ERVEN A
SET A.GEOMETRY_TEST = TROW.GEOM
WHERE A.SEQ = TROW.SEQ;
ELSE
DBMS_OUTPUT.PUT_LINE('GEOMETRY NOT VALID WITH ORA-' ||TROW."VALIDATION"|| ' ON SEQ'||TROW.SEQ);
END IF;
END LOOP;
END;
The values it returns is an blank GEOMETRY.
Any help would be appreciated.
Thanks in advance
