Answer by i alarmed alien for How to parse category term from Wordpress ATOM feed in PHP?

term is an attribute, so you need to use getAttribute to get the data from it. For example:

// $dom is the DOMDocument object holding the XML$cats = $dom->getElementsByTagName('category');foreach ($cats as $c) {    echo "term: " . $c->getAttribute('term') . PHP_EOL;}

Output:

term: Blogterm: Mobileterm: Websites

If you're using $c->nodeValue, you won't get anything because the node doesn't have a value--it's empty. To get the first category's term attribute, you'll need to substitute your current line with this:

'cats' => $node->getElementsByTagName('category')->item(0)->getAttribute('term')
