XML : php load xml but xml does work simplexml_load_string

Hello I have been trying a lot of loading xml via php but from my vps error log I always got error.

PHP Warning: Invalid argument supplied for foreach() Trying to get property of non-object

So far this what I have created

  xml.php  <?php    $url = "test.xml";  $ch = curl_init();  curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);  curl_setopt($ch, CURLOPT_URL, $url);    $data = curl_exec ($ch);  curl_close($ch);    $xml = simplexml_load_string($data);    $con = mysql_connect("localhost","root","mypassw0rd");  mysql_select_db("test_xml",$con) or die(mysql_error());    foreach($xml -> item as $row){      $title = $row -> title;      $destination = $row -> destination;      $price = $row -> price;      mysql_query("INSERT INTO `tblxml` VALUES('NULL','$title','$destination','$price')") or die(mysql_error());    }    ?>    

test.xml

  <item>      <title>      title 1      </title>        <destination>      destination 1      </destination>        <price>      price 1      </price>  </item>    

table structure

  CREATE TABLE IF NOT EXISTS `tblxml` (    `id` int(11) NOT NULL AUTO_INCREMENT,    `title` text NOT NULL,         `destination` text NOT NULL,    `price` text NOT NULL,    PRIMARY KEY (`id`)  ) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=8 ;    

xml and php both on the same folder.

Any help would appreciate.
