it just needs to use the \d+ as you did.Not sure what you mean. Your code did not produce any rows for id1=6:
SQL> with x as (select 6 as id1, ';;;' path from dual)
  2  --
  3  -- end of test data
  4  --
  5  select id1, regexp_substr(path,'\d+',1,rn) as path

  7                       from dual
  8                       connect by rownum <= (select max(length(regexp_replace(path,'[^;]'))) from x))
  9  where regexp_substr(path,'\d+',1,rn) is not null
10  order by 1,2
11  /
no rows selected
