Pulls in an overstuffed RSS feed and removes any content:encoded nodes (which are usually superfluous).
<?php
$ch = curl_init("FEED URL GOES HERE");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 5);
curl_setopt($ch, CURLOPT_USERAGENT, "Henry's very friendly feed fetcher v1.1");
$rss_string = curl_exec($ch);
$dom = new DOMDocument();
$dom->loadXML($rss_string);
$contents = $dom->getElementsByTagNameNS('http://purl.org/rss/1.0/modules/content/', 'encoded');
while ($contents->length > 0) {
$contents->item(0)->parentNode->removeChild($contents->item(0));
}
header('Content-Type: text/xml');
print( $dom->saveXML() );
