从rar加载xml文件（由用户上传）

Using the following code to get content but it gives warning message i.e Message: simplexml_load_file(): I/O warning : failed to load external entity

    $rar_file = rar_open($_FILES['hotelXml']['tmp_name']);
    $list = rar_list($rar_file);
    foreach($list as $file): 
        $xml=simplexml_load_file($file->getName()) or die("Error: Cannot create object");

    endforeach;

$_FILES['hotelXml'] has the rar file that contains xml files
