Php没有读取xml数据

Question

您好我从expedia获取xml feed并尝试将其解析到屏幕上。 它没有返回数据，我无法弄清楚原因。 唯一会返回的是activePropertyCount。 如果你想看一下我在这里的网址： http ： //travellinginmexico.com/test/index.php这里是我要解析的xml： http ： //travellinginmexico.com/测试/ data.xml中

我的代码：

<?php 
$post_string = 'type=xml&cid=55505&minorRev=5&apiKey=4sr8d8bsn75tpcuja6ypx5g3&locale=en_US&currencyCode=USD&customerIpAddress=10.184.2.9&customerUserAgent=Mozilla/5.0+(Windows+NT+6.1)+AppleWebKit/535.11+(KHTML,+like+Gecko)+Chrome/17.0.963.79+Safari/535.11&customerSessionId=&xml=<HotelListRequest><arrivalDate>04/05/2012</arrivalDate><departureDate>04/07/2012</departureDate><RoomGroup><Room><numberOfAdults>2</numberOfAdults></Room><Room><numberOfAdults>2</numberOfAdults><numberOfChildren></numberOfChildren></Room></RoomGroup><city>Cancun</city><countryCode>MX</countryCode><supplierCacheTolerance>MED_ENHANCED</supplierCacheTolerance></HotelListRequest> ';
$path = "http://api.ean.com/ean-services/rs/hotel/v3/list"; //Relative path to the file with $_POST parsing
$ch = curl_init($path); 
$fp = fopen('data.xml','w');
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string); //Send the data to the file
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/xml')); 
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FILE, $fp);
$val = curl_exec($ch);
curl_close($ch);//Close curl session
fclose($fp); //Close file overwrite

 $data = simplexml_load_file('data.xml');
    echo "<ul id=\"data\">\n";
    foreach ($data as $info):
        $title=$info->HotelList;
        $add=$info->address1;
        $count=$info['activePropertyCount'];
        echo "<li><div class=\"title\">",$title,"</div><div class=\"artist\">by ",$add,"</div><time>",$count,"</time></li>\n";
    endforeach;
    echo "</ul>";

?>

Answer 1

您似乎没有尝试从XML对象的正确部分检索数据。 我已将您的代码更新为从HotelList-> HotelSummary部分读取，现在它将正确显示酒店名称和地址。

//Use Curl to get XML here.

$data = simplexml_load_file('data.xml');

//Uncomment this to view the parsed XML on screen.
/*
echo '<pre>';
print_r($data->HotelList);
echo '</pre>';
*/

echo "<ul id=\"data\">\n";
foreach($data->HotelList->HotelSummary as $info):
    $title=$info->name;
    $add=$info->address1;
    $count=$data->HotelList['activePropertyCount'];
    echo "<li><div class=\"title\">",$title,"</div><div class=\"artist\">by ",$add,"</div><time>",$count,"</time></li>\n";
endforeach;
echo "</ul>";

我建议检查libxml_get_errors 。 关于如何在函数的PHP文档中使用它，有一个相当好的例子。 它应该能够告诉你在simplexml_load_file期间发生了什么问题。

如果您认为问题来自cURL（或者更彻底一点），您也可以使用cURL错误函数。 （例如curl_error ）。
