You'll probably need regex support in order to do this. I'd suggest you
use pcre. The regex would be something like:
(.)[a-z-]{10}[ \t]+([0-9]+)[ \t]+([^ \t])+[ \t]+([^ \t]+)[ \t]+([0-9]+)[
\t]+....(etc.)

The bracketed expressions can then be got after doing a pcre_exec as
back references.

Another option: Looks like you want to get file names in a directory. In
that case, why don't you simply use this (pseudo code - just shows the
UNIX API calls to make):
        opendir()
        while (NULL != readdir())
        {
                lstat(&s, name);
        }
        closedir()
This will get you all file names and their attributes like file type
(S_ISREG, S_ISDIR, etc.), file size, etc.

Hope this helps.
