How to match 10 numbers with or without spaces with regex?

@domenico 

To match 10 numbers with or without spaces using regex, you can use the following pattern:

1

d{1,3}(?:s?d{3}){2}

Explanation:

• d{1,3}: Matches 1 to 3 digits
• (?:s?d{3}){2}: Matches exactly 2 occurrences of space followed by 3 digits

This pattern will match 10 numbers with or without spaces, such as:

• 1234567890
• 123 456 7890

If you want to allow for more or fewer spaces between the numbers, you can modify the pattern accordingly.
