Regular expression to match phone numbers with country codes

Question

This is the regular expression I use to match phone numbers like:

00 00 00 00 00
00 00 0 00 00 00 00
+00 0 00 00 00 00

(\\d{2}\\s+\\d{2}\\s+\\d{2}\\s+\\d{2}         


        

Answer 1

1. Where you have your alternative formats listed like:

   (...)\s+(...)\s+(...)
   

   Change that to use the | (OR) operator:

   (...)|(...)|(...)
   

2. Don't escape the parentheses. \( and \) should be simply ( and ).

3. In your third group the + at the beginning should be escaped with a backslash:

   (\+\d{2}\s+\d\s+\d{2}\s+\d{2}\s+\d{2}\s+\d{2})
