Count pattern of a string

Problem: I have a string '01234(01)3423(32)' and I want to count the pattern of this string. I consider as pattern '0','1','2','3','4','(01)','3','4','2','3','(32)' --> pattern=11. If I use 'size' or 'length', this function count as pattern '(' '0' '1' ')' that i consider all togheter as one pattern '(01)'. Can you give me some suggestions to solve the problem?

Count the substrings:

>> S = '01234(01)3423(32)';
>> numel(regexp(S,'(\(\d+\)|\d)'))
ans =  11

And check that it matches the correct substrings:

>> regexp(S,'(\(\d+\)|\d)','match')
ans =
  0
  1
  2
  3
  4
  (01)
  3
  4
  2
  3
  (32)
