First, although this does work, I don't know if it's what you want to do.
You'll end up with a structure like this:
Array (
[0] => stdClass Object
( [countryContinent] => North America )
[1] => stdClass Object
( [countryName] => Canada ) )
Not very useful, as you've found.

I think this is along the lines of what you want to do:
$continent = 'North America';
$landmass[$continent][] = 'Canada';
$landmass[$continent][] = 'United States';
$landmass[$continent][] = 'Mexico';
$continent = 'Asia';
$landmass[$continent][] = 'Japan';
$landmass[$continent][] = 'China';
$landmass[$continent][] = 'Korea';
// sort continents then countries
ksort($landmass); // use ksort() to sort by key
foreach($landmass as $conti => $cntry) { sort($landmass[$conti]); }
print_r($landmass);
There's your array, just loop over it as you like, to do your output.
If you're reading an XML file, you might look into PEAR, which has
packages for parsing and building data structures of XML data.
