How to parse data from a xml into a table and make it update changes live

I have stumbled upon a bit of a issue and I'm hoping that I can get some help/pointer here how to overcome it.

I have an external xml file that I need to parse and display in the table. I did this. The issue is that the file is updating every second, so I would like the data in the cells to update "live" as well, according to the changes in xml file.

The problem is that I don't know what should I use to do it. Can anyone please point me into right direction.

<?php
require('simple_html_dom.php');
$html = file_get_html('http://ift.tt/1B2aqUK');
foreach($html->find('response') as $row) {
     $frontdoorlock = $row->find('led1',0)->plaintext;
     $reardoorlock = $row->find('led2',0)->plaintext;
     $fronthandle = $row->find('btn0',0)->plaintext;
     $frontdoor = $row->find('btn1',0)->plaintext;
     $rearhandle = $row->find('btn2',0)->plaintext;
     $reardoor = $row->find('btn3',0)->plaintext;
     $temperature = $row->find('temp0',0)->plaintext;
     $humidity = $row->find('humid0',0)->plaintext;
     $currentdate = $row->find('temp2',0)->plaintext;
     $lastpowered = $row->find('temp3',0)->plaintext;
}  
?>
