CREATE TABLE table_name ( xml ) AS
SELECT XMLTYPE( '<MESSAGE>
<LOCATIONS>
  <LOCATION_ID>9999</LOCATION_ID>
  <LOC_TYPE>S</LOC_TYPE>
  <NAME>Test Location</NAME> 
  <PHONE_NUM>08 </PHONE_NUM>
   <LAST_MODIFIED_BY/>
   <LAST_MODIFIED_DATE/>
   <POS_CODE/>

SELECT DELETEXML(
         xml,
         '//*[not(text())][not(*)]'
       ).getStringVal()
FROM   table_name
