How to randomize SimpleXML object?

I need to randomize a SimpleXML object and output it as a rss feed.


How should this be done?

Thanks

 

convert it to an array and use shuffle? or count the items in the simplexml file and push each # into an array and shuffle that then use it to loop through the xml.

like so (untested but basic idea should work) :

 <?php
$xml = simplexml_load_file($yourfile);
$xml_cnt = count($xml->items);
    $allitems = range(0,$xml_cnt);
    $all = shuffle($allitems);

foreach($all as $curr) 
{

// output here.

}

?>
