You can copy the inc file in include directory. In include/categories.php just before "?>" put

require_once $xcart_dir."/include/simplepie.inc";
$feed = new SimplePie();
if($cat == 252)
 $feed->set_feed_url("http://www.promartsupplements.co.uk/...nes/?feed=rss2");
else
 $feed->set_feed_url("http://www.promartsupplements.co.uk/blog/?feed=rss2");
 
$feed->init();
// Limit the items to be shown
$i = 0;
$new_feed = array();
foreach($feed->get_items() as $item) {
 if($i <= 2) {
$new_feed[$i]["link"] = $item->get_permalink();
$new_feed[$i]["title"] = $item->get_title();
$new_feed[$i]["descr"] = substr($item->get_description(),0,180);
 
$i++;
 }
}
$smarty->assign("new_feed", $new_feed);

Then use $new_feed in the template you want it to show

 
{foreach from=$new_feed item=nf}
<a href="{$nf.link}">{$nf.title}</a>
<br />
{$nf.descr}
