http://api.ean.com/ean-services/rs/hotel/v3/list?cid=55505&minorRev=12&apiKey=2hkhej72gxyas3ky6hhjtsga&locale=en_US¤cyCode=USD&customerIpAddress=10.184.2.9&customerUserAgent=Mozilla/5.0+(Windows;+U;+Windows+NT+6.1;+en-US;+rv:1.9.2.25)+Gecko/20111212+Firefox/3.6.25&customerSessionId=&xml=<HotelListRequest><arrivalDate>01/22/2012</arrivalDate><departureDate>01/24/2012</departureDate><RoomGroup><Room><numberOfAdults>1</numberOfAdults><numberOfChildren>1</numberOfChildren><childAges>4</childAges></Room></RoomGroup><city>Amsterdam</city><countryCode>NL</countryCode><supplierCacheTolerance>MED</supplierCacheTolerance></HotelListRequest>

If I try;
如果我尝试;
$url = 'http://api.ean.com/ean-services/rs/hotel/v3/list?cid=55505&minorRev=12&apiKey=2hkhej72gxyas3ky6hhjtsga&locale=en_US¤cyCode=USD&customerIpAddress=10.184.2.9&customerUserAgent=Mozilla/5.0+(Windows;+U;+Windows+NT+6.1;+en-US;+rv:1.9.2.25)+Gecko/20111212+Firefox/3.6.25&customerSessionId=&xml=<HotelListRequest><arrivalDate>01/22/2012</arrivalDate><departureDate>01/24/2012</departureDate><RoomGroup><Room><numberOfAdults>1</numberOfAdults><numberOfChildren>1</numberOfChildren><childAges>4</childAges></Room></RoomGroup><city>Amsterdam</city><countryCode>NL</countryCode><supplierCacheTolerance>MED</supplierCacheTolerance></HotelListRequest> ';
$xml = simplexml_load_file($url);
I get met with the following error;
我遇到了以下错误；
Warning: simplexml_load_file() [function.simplexml-load-file]: http://api.ean.com/ean-services/rs/hotel/v3/list?cid=55505&minorRev=12&apiKey=2hkhej72gxyas3ky6hhjtsga&locale=en_US¤cyCode=USD&customerIpAddress=10.184.2.9&customerUserAgent=Mozilla/5.0%2B(Windows;%2BU;%2BWindows%2BNT%2B6.1;%2Ben-US;%2Brv:1.9.2.25)%2BGecko/20111212%2BFirefox/3.6.25&customerSessionId=&xml=%3CHotelListRequest%3E%3CarrivalDate%3E01/22/2012%3C/arrivalDate%3E%3CdepartureDate%3E01/24/2012%3C/departureDate%3E%3CRoomGroup%3E%3CRoom%3E%3CnumberOfAdults%3E1%3C/numberOfAdults%3E%3CnumberOfChildren%3E1%3C/numberOfChildren%3E%3CchildAges%3E4%3C/childAges%3E%3C/Room%3E%3C/RoomGroup%3E%3Ccity%3EAmsterdam%3C/city%3E%3CcountryCode%3ENL%3C/countryCode%3E%3CsupplierCacheTolerance%3EMED%3C/supplierCacheTolerance%3E%3C/HotelListRequest%3E%20:1: parser error : Start tag expected, '<' not found in C:\Program Files\XAMPP\xampplite\htdocs\hotel\results.php on line 29
The most notable part of that error is: parser error : Start tag expected, '<' not found
该错误最值得注意的部分是：解析器错误：预期开始标记，未找到“<”
I would like to access that file and use PHP/SimpleXML to format the results - but thus far I am stuck.
我想访问该文件并使用 PHP/SimpleXML 来格式化结果 - 但到目前为止我被卡住了。
I thought that this thread HEREwhich talks about rawurlencode may have helped but it didn't, either that or I'm missing something.
我认为这里讨论 rawurlencode 的这个线程可能有所帮助，但它没有，或者我错过了一些东西。

The results are coming back as json. Replace simplexml_load_filewith json_decodeand you will see a proper object.
结果以 json 形式返回。替换simplexml_load_file为json_decode，您将看到一个合适的对象。
If you want to use xml, you need to specify it in the headers. The following code will return valid xml:
如果要使用 xml，则需要在 headers 中指定它。以下代码将返回有效的 xml：
$context = stream_context_create(array('http' => array('header' => 'Accept: application/xml')));
$url = 'http://api.ean.com/ean-services/rs/hotel/v3/list?cid=55505&minorRev=12&apiKey=2hkhej72gxyas3ky6hhjtsga&locale=en_US¤cyCode=USD&customerIpAddress=10.184.2.9&customerSessionId=&xml=<HotelListRequest><arrivalDate>01/22/2012</arrivalDate><departureDate>01/24/2012</departureDate><RoomGroup><Room><numberOfAdults>1</numberOfAdults><numberOfChildren>1</numberOfChildren><childAges>4</childAges></Room></RoomGroup><city>Amsterdam</city><countryCode>NL</countryCode><supplierCacheTolerance>MED</supplierCacheTolerance></HotelListRequest> ';
$xml = file_get_contents($url, false, $context);
$xml = simplexml_load_string($xml);
print_r($xml);
?>
