you must put
你必须把
$Rate = $xml->Currencies->Currency['1']->Rate;
instead of
代替
$Rate = $xml->Currency[1]->Rate;
because of $xmlstructure is
因为$xml结构是
SimpleXMLElement Object
(
[Date] => 20130530
[Currencies] => SimpleXMLElement Object
(
[Currency] => Array
(
[0] => SimpleXMLElement Object
(
[ID] => AED
[Units] => 1
[Rate] => 0.14900000
)
[1] => SimpleXMLElement Object

You are missing 'Currencies' in your code. It should be:
您的代码中缺少“货币”。它应该是：
$url = 'http://www.bank.lv/vk/xml.xml?date=20130530';
$xml = simplexml_load_file($url) or die("feed not loading");
$Rate = $xml->Currencies->Currency[1]->Rate;
echo $Rate;
