解析XML属性PHP

我试图在每个routeTitle下回显minutes属性。

XML：http：//webservices.nextbus.com/service/publicXMLFeed？command = predictions＆a = ttc＆stopId = 1974

<?php

$stopid="1974";
$urlbase = "http://webservices.nextbus.com/service/publicXMLFeed?command=predictions&a=ttc&stopId=";
$url = $urlbase.$stopid;

$xml = simplexml_load_file($url);
$rt = $xml->predictions;

foreach ($rt as $value) {
    echo $value->attributes()->routeTitle."Min. <br>";
}

echo $rt->direction->attributes()->minutes;

?>

因此，例如：

325-Don Mills
3 Min.
1 Min.
185-Don Mills Rocket
2 Min.
1 Min.
25-Don Mills
2 Min.
1 Min.

更新的问题：如何访问正确的节点并避免出现“警告：main（）：节点不再存在...”？

如果要回显每个routeTitle的minutes属性值，则循环应如下所示：foreach

// your code

foreach ($rt as $value) {
    echo $value->attributes()->routeTitle . '<br />';
    if(isset($value->direction)){
        foreach($value->direction->prediction as $attr){
            foreach($attr->attributes() as $k => $v){
                if($k == 'minutes'){
                    echo $v . ' minutes <br />';
                }
            }
        }
    }else{
        echo "No direction. <br />";
    }
}
