You don't need any library to parse text.
Thanks Erel, but it wasn't really about parsing text. That's straightforward enough.
For some reason, I thought that the Stringfunctions class had some functionality specifically dedicated towards phone numbers. But that was obviously some other site.
But yeah, it turns out that the entry form which produces these numbers, forces an area code, and only accepts U.S. numbers. So, all I had to do was sPhone.Replace() dashes, spaces, and parentheses with blanks, generating a canonical form 9999999999, which was then parsed out easily.
All set, thanks.
