First off a little introduction is in order to the scenario I was in, because I am sure someone else out there will eventually be in a similar situation.
I am working on developing a system for a client which involves sending a validation code to a user's mobile phone in the form of an SMS. Because we wanted to avoid the whole hassle of forcing the user to include their country code in the prefix of their mobile number (since let's face it, most of us probably don't know it unless we've made international calls before), the idea was to simply determine this based on the country the user lives in.
Now because I always store the user's country in the database in the IS0 639-1 specification, I needed to have an XML file which basically had a simple structure of the countries code as the tag, and the calling code as the value.
I searched around for a while and didn't find any, so I decided that I was just going to instead look for a site that had the 2 letter country code and the international calling code both in a well structured manner which I could scrape from. Thus, I built a small data-mining/scraping script which pulled in all the data, used some regular expressions to interpret it and discard all the HTML and low and behold, here is the result:

I hope this helps someone out there! If you need the same thing but using the 3 character country codes instead, let me know and I'll gladly generate one for you.
