phone-number

Hello Everyone,

I am new to Stackoverflow and I have a quick question. Let's assume we are given a large number of HTML files (large as in theoretically infinite). How can I use Regular Expressions to extract the list of Phone Numbers from all those files?

Explanation/expression will be really appreciated. The Phone numbers can be any of the following formats:

(123) 456 7899
(123).456.7899
(123)-456-7899
123-456-7899
123 456 7899
1234567899

Thanks a lot for all your help and have a good one!
