passing xml in api and get data in xml with help of curl

[sam230]

http://api.ean.com/ean-services/rs/hotel/v3/list?minorRev=4&cid=55505&apiKey=5q4gzx43g6ukcrq798z2hz75&customerSessionId=&locale=en_US&currencyCode=USD&xml=new%20delhi2

when i call api directly to browser i got right data in xml format.

but when i call it through curl.. sometime i get data in json format or sometimes no data..

$ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,"http://api.ean.com/ean-services/rs/hotel/v3/list?minorRev=4&cid=55505&apiKey=5q4gzx43g6ukcrq798z2hz75&customerSessionId=&locale=en_US&currencyCode=USD&xml=<HotelListRequest><city>new%20delhi</city><RoomGroup><Room><numberOfAdults>2</numberOfAdults><numberOfResults></numberOfResults></Room></RoomGroup></HotelListRequest>");
        curl_setopt($ch, CURLOPT_FAILONERROR,1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
          
        curl_setopt($ch, CURLOPT_TIMEOUT, 15);
        $retValue = curl_exec($ch);                      
        curl_close($ch);
        
        echo $retValue;

try to set the CURLOPT_HTTPHEADER something like this:
curl_setopt($ch, CURLOPT_HTTPHEADER, Array("User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.15) Gecko/20080623 Firefox/2.0.0.15") );

Here ya go...
you need to add an _type variable to your request.
right after currency code and before xml=...
add &_type=xml so:
...&locale=en_US&currencyCode=USD&_type=xml&xml=
