从SimpleXMLElement对象中获取值

我有这样的东西:

$url = "http://ws.geonames.org/findNearbyPostalCodes?country=pl&placename=";
$url .= rawurlencode($city[$i]);

$xml = simplexml_load_file($url);
echo $url."\n";
$cityCode[] = array(
    'city' => $city[$i], 
    'lat' => $xml->code[0]->lat, 
    'lng' => $xml->code[0]->lng
);

它应该从geonames下载XML。如果我执行print_r($xml)，我得到:

SimpleXMLElement Object
(
    [code] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [postalcode] => 01-935
                    [name] => Warszawa
                    [countryCode] => PL
                    [lat] => 52.25
                    [lng] => 21.0
                    [adminCode1] => SimpleXMLElement Object
                        (
                        )

                    [adminName1] => Mazowieckie
                    [adminCode2] => SimpleXMLElement Object
                        (
                        )

                    [adminName2] => Warszawa
                    [adminCode3] => SimpleXMLElement Object
                        (
                        )

                    [adminName3] => SimpleXMLElement Object
                        (
                        )

                    [distance] => 0.0
                )

我这样做，你可以看到$xml->代码[0]->lat，它返回一个对象。我怎样才能得到这个值?

当前回答

foreach($xml->code as $vals )
{ 
    unset($geonames);
    $vals=(array)$vals;
    foreach($vals as $key => $value)
      {
        $value=(array)$value;
        $geonames[$key]=$value[0];
      }
}
print_r($geonames);

其他回答

你可以用这个函数转换数组

function xml2array($xml){
$arr = array();

foreach ($xml->children() as $r)
{
    $t = array();
    if(count($r->children()) == 0)
    {
        $arr[$r->getName()] = strval($r);
    }
    else
    {
        $arr[$r->getName()][] = xml2array($r);
    }
}
return $arr;
}

您可以使用“{}”来访问您的属性，然后您可以按照自己的意愿进行操作。保存或显示内容。

    $varName = $xml->{'key'};

从你的例子中，她就是代码

        $filePath = __DIR__ . 'Your path ';
        $fileName = 'YourFilename.xml';

        if (file_exists($filePath . $fileName)) {
            $xml = simplexml_load_file($filePath . $fileName);
            $mainNode = $xml->{'code'};

            $cityArray = array();

            foreach ($mainNode as $key => $data)        {
               $cityArray[..] = $mainNode[$key]['cityCode'];
               ....

            }     

        }

header("Content-Type: text/html; charset=utf8");
$url  = simplexml_load_file("http://URI.com");

 foreach ($url->PRODUCT as $product) {  
    foreach($urun->attributes() as $k => $v) {
        echo $k." : ".$v.' <br />';
    }
    echo '<hr/>';
}

您必须将simpleXML Object转换为字符串。

$value = (string) $xml->code[0]->lat;

$codeZero = null;
foreach ($xml->code->children() as $child) {
   $codeZero = $child;
}

$lat = null;
foreach ($codeZero->children() as $child) {
   if (isset($child->lat)) {
      $lat = $child->lat;
   }
}
