I have no idea. I mean, I haven't used PCRE, I used regular expressions in 
Perl. So the answer is somewhere in PCRE and Octave documentation.

Looking into http://www.pcre.org/pcre.txt I see:

In  addition  to  the  main compiling and matching functions, there are
       convenience functions for extracting captured substrings from a subject
       string that is matched by pcre_exec(). They are:

         pcre_copy_substring()
         pcre_copy_named_substring()
         pcre_get_substring()
         pcre_get_named_substring()
         pcre_get_substring_list()
         pcre_get_stringnumber()
         pcre_get_stringtable_entries()

       pcre_free_substring() and pcre_free_substring_list() are also provided,
       to free the memory used for extracted strings.

- I think this is the piece to start from.

  Sergei.
