Regex matches

. = any character
^. = any character at the begining
{5} = length of characters to look for
\/ = match /
\| = match |
^.{5}\/ = matches any of the first 5 charaters that end with /
(^.{5}) = first 5 characters

\d{1,5}\s\w+\.
"a digit" \d "between" {1,5} "1 to 5 digits in length" \s "followed by a space" \w "with characters.." + "with one or more characters" \. "ending with a ."

(?:[0-9])+ = Matches any numbers after the first letter....ie: A0012/B0012/D0032 matched: 0012 0012 and 0032
