Why Isnt This Working?

I've been spending hours trying to figure this out... why isn't this working to parse this: http://developer.trulia.com/docs/LocationInfo/getNeighborhoodsInCity

<?php
 

// Construct the GetPriceResearch REST call 
$apicall = "http://api.trulia.com/webservices.php?library=LocationInfo&function=
getNeighborhoodsInCity&city=Seattle&state=WA&apikey=MY_KEY";

// Load the call and capture the XML document returned by API
$xml = file_get_contents($apicall);


// Check to see if the XML response was loaded, else print an error
if ($xml) {
	$results = '';

	if( $xml->Errors )
	{
		// If there was an error in the response, print a warning.
		$results = "Uh oh, there was an error making the query!";
	}
	else
	{
		// Gather our statistics
		$LocationInfo = $xml->LocationInfo;

		$city = $LocationInfo->city;
		$state = $LocationInfo->state;
		$neighborhood = $LocationInfo->neighborhood['name'];

		$results .= "<b>city:</b> $city<br/>";
		$results .= "<b>state:</b> $state<br/>";
		$results .= "<b>neighborhood:</b> $neighborhood<br/>";

	}
}
// If there was no XML response, print an error
else {
	$results = "Dang! Must not have got the XML response!";
}

?>

PHP:

 

I would try debugging the situation: first parse the XML, and then try print_r($var) to see what the variable looks like. Posting that here would help me.

 

file_get_contents() doesn't return an object. I guess you're looking for something like simplexml_load_file().

 

rcadble, you've been alot of help to me... unfortunately I don't know how to do what you stated above.

nico_swd, I tried simplexml_load_file($api_call); & it didnt work for me
