return only Digits 0-9 from a String

Question

I need a regular expression that I can use in VBScript and .NET that will return only the numbers that are found in a string.

For Example any of the following \"str

Answer 1

I don't know if VBScript has some kind of a "regular expression replace" function, but if it does, then you could do something like this pseudocode:

reg_replace(/\D+/g, '', your_string)

I don't know VBScript so I can't give you the exact code but this would remove anything that is not a number.

EDIT: Make sure to have the global flag (the "g" at the end of the regexp), otherwise it will only match the first non-number in your string.

Answer 2

By the looks of things, your trying to catch any 10 digit phone number....

Why not do a string replace first of all on the text to remove any of the following characters.

<SPACE> , . ( ) - [ ] 

Then afterwards, you can just do a regex search for a 10 digit number.

\d{10}
