I would suggest parsing the XML data such that you have an array of
continents, and each element of said array is an array with two elements
- the first being the contintent name and the second array containing
all countries within that continent.
So, after parsing the file you would have:
$contintents[0] = array('North America',array('Canada','United
States','Mexico'));
$contintents[1] = array('South
America',array('Ecuador','Chile','Peru','Columbia','Brazil'));
etc. etc.
HTH.
