Php Catalyst XML数据源

我试图从一个XML文件datafeed输出数据，支持文档非常糟糕，我在循环XML时遇到了问题

SimpleXMLElement Object ( 
    [@attributes] => Array (
        [version] => 6 [type] => WEB [date] => 20120220 ) 
        [account] => SimpleXMLElement Object ( 
        [@attributes] => Array (
            [code] => XXXX 
        ) 
        [sites] => SimpleXMLElement Object ( 
            [site] => SimpleXMLElement Object ( 
                [@attributes] => Array (

                ) 
                [name] => Name [address1] => Address 1 [address2] => town [address3] => UK [county] => County [postcode] => Postcode [phone] => 0123456789 [fax] => 0123456789
                [vehicles] => SimpleXMLElement Object ( 
                    [vehicle] => Array ( 
                        [0] => SimpleXMLElement Object ( 
                            [@attributes] => Array ( 
                                [code] => 5956 [new] => N
                                [engineSize] => 998 
                                [mileage] => 8000 
                                [type] => MC

                                [modified] => 20110928090130 
                            ) [manufacturer] => Honda 
                            [description] => CBR 1000 RR-7 
                            [colour] => Black 
                            [body] => Motorcycle 
                            [fuel] => Petrol 
                            [status] => In Stock 
                        ) 
                        [1] => SimpleXMLElement Object ( 
                            [@attributes] => Array (
                                [code] => 5958 
                                [new] => Y 
                                [engineSize] => 125 
                                [type] => MC 
                                [created] => 20110930090254 
                                [modified] => 20110930090254 
                            ) 
                            [manufacturer] => Honda 
                            [description] => WW125EX2A 
                            [colour] => BLACK(NHA35) 
                            [body] => SCOOTER 
                            [status] => In Stock 
                            [category] => SCOOTER 
                        )
                    ) 
                )
            )
        )
    )

数据通过以下方式加载：

$request = 
    "<"."?xml version='1.0' encoding='iso-8859-1'?".">".
        "<download account='XXXX' password='XXXX' version='6' request='EXP' format='XML' dealer='XXXX' vehicles='Y' />";

$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/xml", "Content-Length: " . strlen($request)));

curl_setopt($ch, CURLOPT_POSTFIELDS, $request);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_URL, 'https://www.catalyst-findit.co.uk/download.php');
$response = curl_exec($ch);

$xml = simplexml_load_string($response);
print_r($xml);

虽然这似乎不起作用

如果有人能提供任何建议，请心存感激：）

提前谢谢

使用XPath搜索特定节点数据

$text = <<<EOF
... XML data ...
EOF;

$xml = new SimpleXMLElement($text);
# register xpath prefix for default namespace
$namespaces = $xml->getDocNamespaces();
$xml->registerXPathNamespace('__ns', $namespaces['']);
# get first vehicle data
$result = $xml->xpath('//__ns:vehicles/__ns:vehicle[1]');
# get all vehicles in array
$vehicles = $xml->xpath('//__ns:vehicles/__ns:vehicle');

print_r($result); # or
echo($result[0]->colour); 

foreach ($vehicles as $v) {
    echo ($v->colour . "\n");
}

$text=xpath（'//\uu-ns:vehicle/\uu-ns:vehicle[1]”）；
#把所有车辆排成一排
$vehicles=$xml->xpath（'//\u-ns:vehicles/\u-ns:Vehicler'）；
打印（$result）；#或
回声（$result[0]->颜色）；
foreach（车辆为$v）{
回声（$v->颜色。“\n”）；
}

错误是什么？请尝试

curl\u error

获取错误没有显示错误，

print\u r

显示上述数据，我只是无法访问车辆数据。我测试并修复了（必须使用名称空间）示例代码：）谢谢！这很好，如果可能的话，你可以在一个循环中演示它，这样就不必指定车辆编号了吗？我添加了更多的示例代码。如果xpath中没有[1]，则会得到数组中的所有车辆（如注释中所述）。
