Help with Ajax Dropdown List

[RandomTom]

I'm creating a 3 tier dropdown list to be called upon by PHP/Ajax similar to these two examples:

Only problem is I don't know how to call the countries up without having them all listed in the HTML (which is less than ideal) This XML list tries to help:

But I'm struggling, being a bit of a newbie and all. Any help would be great, thanks.

So in the HTML call 'UK' for United Kingdom to come up? Saving a few characters is the best way rather than getting the list upon clicking the dropdown?

Thanks though.
