$xmlfile = "http://www.statbox.co.uk/demo/statinfo.xml";

function getarray($xmlfile) {

$xml = simplexml_load_file($xmlfile);
$endarray = array();
$loadarray = array();
$xmlnode = 0;
$end = 1;

while ($end == 1) {
	$xmlhits = $xml->browser->browser[$xmlnode];
	$xmlkey = $xml->browser->browser[$xmlnode]['name'];

	if ($xmlhits != "") {
		echo "<br>$xmlkey : $xmlhits";
		$temparray = array($xmlkey => $xmlhits);
		$loadarray = array_merge($loadarray, $temparray);
	//	$endarray = array_merge($endarray, $loadarray);
	} else if ($xmlhits == "") {
