$feed = file_get_contents($searchurl); $xml = new simplexmlelement($feed);  foreach ($xml->channel->item $entry){   echo $entry->title;   echo $entry->description; }

i error message:

warning: simplexmlelement::__construct() [simplexmlelement.--construct]: entity: line 21: parser error : input not proper utf-8, indicate encoding !

i notice feed downloaded not have line @ top, might explain error.

<?xml version="1.0" encoding="utf-8"?>

$feed = utf8_encode(file_get_contents($searchurl));
