Php not reading xml data - php

Question

Hello I am getting xml feed from expedia and trying to parse it onto the screen. It is not returning the data, and I can not figure out why. the only thing that will return is activePropertyCount. Here is the url where I am doing this if you want to take a look: http://travellinginmexico.com/test/index.php and here is the xml that I am trying to parse: http://travellinginmexico.com/test/data.xml
My code:
<?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

It appears that you are not trying to retrieve your data from the correct part of the XML object. I have updated your code to read from the HotelList->HotelSummary section, and it will now display the hotel name and address properly.
//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>";

I recommend checking out libxml_get_errors. There's a fairly good example on how to use it in the PHP documentation for the function. It should be able to tell you what problems are occurring during simplexml_load_file.
If you think the problem is coming from cURL (or to be a little more thorough) you can use the cURL error functions as well. (Such as curl_error).
