Regex code for product models and codes - regex

Question

I found a very useful regex code in order to extract product codes here, this is the expression:
\b((?:[a-z]+\S*\d+|\d\S*[a-z]+)[a-z\d_-]*)\b
It works almost perfectly, but I need to detect and extract only the product codes that have a length of at least 5 digits.
For example, for the following strings:
5T COFFEE BREW FOR BLACK & DECKER DCM-601B
10T COFFEE BREW FOR BLACK & DECKER DCM-1100B
10T COFFEE BREW FOR BLACK & DECKER DCM-1100W
8T COFFEE BREW FOR BLACK & DECKER CM-1509

I get:

How can I do this?

Answer 1

If we assume that your codes contain 5 or more non-whitespace symbols, and there must be at least 1 digit, the regex for the codes will be:
\b(?!\d+\.\d+)(?=\S*\d)\S{5,}\b
See Demo 1
The (?!\d+\.\d+) disallows float/decimal numbers like 1.2345 or 12.44.

Answer 2

I'm not quite sure if I understood your question, but you can use a regex like this to get the product codes you want:
((?:\w{2,}\.)?\w{1,}[.\/-]?\d+\w+)(?=\b)
