title: .NET Filtering compare countries xml to countries in database
body: <p>I have a .net app that is using a countries.xml to populate a dropdown of countries called from ajaxToolkit webservice method. The box populates the all countries and is required for subsequently populating the regions then cities. </p>
  
  <p>I would only like to show countries that are in the users table in the mssql database. Is there a way to do this without re-writing all the code? Like filtering the results using a compare or something?</p>
