include("connection.php")

$xmlUrl = "import_dubai.xml"; // XML ไฟล์   
$xmlStr = file_get_contents($xmlUrl);  
$xml = preg_replace('#&(?=[a-z_0-9]+=)#', '&amp;', $xmlStr);

foreach($xml -> Listing as $Listing1){       // Listing => array
   foreach($Listing1 -> Listing as $Listing){    // Listing => array
           $Listing = $Listing -> Listing;
           $count = $Listing -> count;                               
       foreach($Listing -> Images as $Images){   // Images => array
                  $image = $Images -> image;
                  echo '<br>'.$Listing1 -> Listing.' '.$Listing -> count.' '.$Listing -> Images.' '.$Images -> image. '<br>';
                  $result=mysql_query("insert into xml_image ('xml_id','image_url') values ('$count','$image')");
                }
                                                        
        }
}

if (!$result){
        echo 'Mysql Error';
} else{
    echo ' Success';    
}
