Regular Expression Help With Phone Number

[Guest]

I have a sentence, for example, "My telephone number is (717) 999-9834". What would be the regex expression to just extract the area code, in this case, 717. I have gotten as far as a regex that gets (717), but need help stripping out the (). Here is what i have so far:

Thanks for your help.

Hi aparsons ,
You can get your area code , using the string function MID(string,start , count) as following way:

<cfoutput>
#mid(mysentence,a_ac1+1,3)#
</cfoutput>
since a_ac1 has the starting index of the ( ,so you have to start one character ahead , and count = 3 since your area code of 3 character

Thanks.

Ok. Yeah, I guess that will work. I was trying to keep it on one line of code.
