I have a feed that is not valid RSS nor standard and can not be changed. I would like to pull elements of this feed like recent snow fall and current temperature.

Can anyone tell me what I need to do to pull the data from this feed:
http://common.snow.com/adminincludes/rtp.resorts.vri.xml.asp

I'm using Zend_Feed_Reader but I get an error that says the Feed is Invalid or not supported.

I've also tried Zend_Dom_Query to get the data but I'm stuck in the arrays and am not sure how to pull that data out. I thought maybe there was an easier way to do this through XSL Transformation or something of the like.

Thanks for any guidance.

Here is an example of my path down Dom_Query land:

$url = 'http://common.snow.com/adminincludes/rtp.resorts.vri.xml.asp';
            $client = new Zend_Http_Client($url);
            $response = $client->request();
            $html = $response->getBody();
            $dom = new Zend_Dom_Query($html);
            
            if(sizeof($dom->query('resort')) > 0) {
                  $resort = $dom->query('resort');
            } else {
                  $resort = NULL;
            }
            
            if($resort != NULL) {
                  foreach($resort as $index=>$result) {
                        if($result->nodeValue !== '') {
                              $resort = $result->nodeValue;
                        }
                  }
            }
            
            $data = array(
                  'resort'=>$resort,
                  'other'=>'variable'
            );
            $xml = (object) $data;
            var_dump($xml); die;

This is the dump with $resort not holding any data:
object(stdClass)#53 (2) { ["resort"]=> string(27) " " ["other"]=> string(8) "variable" }

Thanks

Did you ask Jeff about how other customers use the feed?

The XML is fairly "information-dense" (a good thing!) and I do not see anything wrong with it.  Install this code snippet and run it to see how this works.  Note the use of the "commented out" var_dump() commands - those are very helpful when you are debugging data-dependent issues.

Best of luck with it, ~Ray
<?php // RAY_temp_kent3800.php
error_reporting(E_ALL);

// MAKE var_dump() EASY TO READ
echo "<pre>";

// GET THE XML FROM THE WEB SERVICE AND MAKE AN OBJECT
$url = 'http://common.snow.com/adminincludes/rtp.resorts.vri.xml.asp';
$xml = trim(file_get_contents($url));
$obj = SimpleXML_Load_String($xml);

// ACTIVATE THIS TO SEE THE OBJECT
// var_dump($obj);

// GET INFORMATION FROM THE OBJECT
foreach ($obj->resort as $r)
{
    // var_dump($r);
    $d = $r["description"];
    $s = $r->snowreport;
    // var_dump($s);
    $t = $s->temperature;
    $n = $s->newsnow;
    $f = (string)$s->temperature["fahrenheit"];
    $l = (string)$n->last24hours["inches"];

    // REPORT THE CONDITIONS
    echo PHP_EOL . "$d  {$f}&deg;F, {$l}\" NEW SNOW";
}
