Parsing unusual tags in rss feed using php. (Have the tag <dc:author>)

I have researched this but have had trouble implementing it into my code. I have:

<?php
$rss = new DOMDocument();
$rss->load('FEEDURL');
$feed = array();
foreach ($rss->getElementsByTagName('item') as $node) {
$item = array ( 
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,

//author
'author' => $node->getElementsByTagNameNS('http://purl.org/dc/elements/1.1/','dc') >item(0)->nodeValue

);
array_push($feed, $item);
}
?>

the section with the comment //author is where I am having problems. The tag in the RSS Feed is <dc:author>

If you have a relevant article that I have missed, please send me there and don't vote down. Thanks :)

Solution

  • dc is namespace, author is a tag name, so if http://purl.org/dc/elements/1.1/ is namespaceURI for dc you need to search like this:

    $node->getElementsByTagNameNS('http://purl.org/dc/elements/1.1/','author')
