The parameters for the http://ec.europa.eu/taxation_customs/vies/viesquer.do method need to have the validated number country code under 'ms', not the requesting country code. Also, I ran into an error page on the isvat service that returns a false positive (a deadline exceeded html error page), so I added a check for any html before returning true.
Finally, i replaced the tabs with spaces since there was a mix of both.
