I believe XML would be the best choice for this. Using XML, you can download
the entire information(including Country-City relationship) at one go.
This would help in three ways:
1. Eliminate the need to get back to the server for getting cities related
to a country
2. No array manipulation needs to be done.
3. No need to reload the full page again.
Hope this helps
