php读取xml文件循环遍历@attributes？

Question

我有一个 exrate.xml 看起来像这样

 <!--For reference only. Only one request every 5 minutes!-->
    <ExrateList>
    <DateTime>5/29/2011 8:54:12 PM</DateTime>
    <Exrate CurrencyCode="AUD" CurrencyName="AUST.DOLLAR" Buy="21688.77" Transfer="21819.69" Sell="22201.6"/>    
    <Source>source name </Source>
    </ExrateList>

任何人都知道如何读取 xml 并输出数据。

我用过

            <?php
              = simplexml_load_file("Service/Forex_Content.xml");
            echo '<pre>';
            print_r($xml);
            echo '</pre>';

        ?>


SimpleXMLElement Object
(
    [DateTime] => 5/29/2011 8:54:12 PM
    [Exrate] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [@attributes] => Array
                        (
                            [CurrencyCode] => AUD
                            [CurrencyName] => AUST.DOLLAR
                            [Buy] => 21688.77
                            [Transfer] => 21819.69
                            [Sell] => 22201.6
                        )

                )

如何循环@attributes 来显示数据？

foreach ($xml as $value){
    foreach ($value->@attributes as $key=>$val){ // I have problem here @attributes

        }

}

使用 SimpleXML，使用 attributes() 方法访问属性:

foreach ($value->attributes() as $key=>$val){
    // do something
}
