Soap request is not working

//PHP CODE
<?php
$xmlData='<OTA_HotelDestinationsRQ Version="1.0">
           <POS>
             <Source>
                  <UniqueId Id="user:password" />
             </Source>
           </POS>
           <DestinationInformation LanguageCode="EN" />
         </OTA_HotelDestinationsRQ>';

$wsdl="http://acceptance.travelstreet.com/hotelsv3/components/Hotels_DestinationsWS.cfc?wsdl";
$client=new SoapClient($wsdl,array('trace' => 1));
try
{

     $res=$client->__call("OTA_HotelDestinationsRQ",array($xmlData));
}
catch (SoapFault $Exception)
{
     echo 'SoapFault Exception';
}
echo $res;
?>

It is showing Internal Server error

Later on i have changed above xml into array using xml2array class and i kept the result in one variable like

$iArray=xml2array($xmlData); Using this i have coded like:

<?php
$xmlData='<OTA_HotelDestinationsRQ Version="1.0">
           <POS>
             <Source>
                  <UniqueId Id="user:password" />
             </Source>
           </POS>
           <DestinationInformation LanguageCode="EN" />
         </OTA_HotelDestinationsRQ>';

$wsdl="http://acceptance.travelstreet.com/hotelsv3/components/Hotels_DestinationsWS.cfc?wsdl";
$client=new SoapClient($wsdl,array('trace' => 1));
try
{

     $res=$client->__call("OTA_HotelDestinationsRQ",$iArray); 
     // (or) also check with bellow st开发者_JS百科atement
     $res=$client->OTA_HotelDestinationsRQ($iArray);
}
catch (SoapFault $Exception)
{
     echo 'SoapFault Exception';
}
echo $res;
?>

It is showing Invalid Xml error
