Frank gave you a solution in your other thread. You could simplify it if you are on 11g:
SQL> select * from table_x
  2  /
TXT
TECHPKG(INTELLI CC+FRT SONAR)
PWRPKG(P/W+P/L+CC)
select  txt,
        regexp_substr(
                      txt,
                      '(.*\()*([^+)]+)',
                      1,
                      column_value,
                      null,
                      2
                     ) element,
        column_value element_number
  from  table_x,
        table(
              cast(
                   multiset(
                            select  level
                              from  dual
                              connect by level <= regexp_count(txt,'\+') + 1
                   as sys.OdciNumberList
  order by rowid,
           column_value
TXT                                      ELEMENT    ELEMENT_NUMBER
TECHPKG(INTELLI CC+FRT SONAR)            INTELLI CC              1
TECHPKG(INTELLI CC+FRT SONAR)            FRT SONAR               2
PWRPKG(P/W+P/L+CC)                       P/W                     1
PWRPKG(P/W+P/L+CC)                       P/L                     2
PWRPKG(P/W+P/L+CC)                       CC                      3
