@godwin: since I can't add a comment to your post and no one else seems to have responded, let me address at least one issue. At the beginning you have

[\d+]{2}\-

\d+ will match one or more digits and you're asking for it to be repeated twice, so the whole segment will match 123456789-:

• [\d+] = 12345678 (greedy matching)
• [\d+] = 9
• \- = -

You also probably didn't need to escape the dash because it's not inside a group block "[]".
