Parse RSS/Atom feeds with PHP's HTML DomDocument - php

Question

How to find the values for namespace content:encoded and dc:creator with the following code
Unfortunately I cannot use simplepie or magpierss or even simplexml.
I know I've to use $doc->getElementsByTagName, but cannot figure out where?
<?php
function rss_to_array($tags, $array, $url) {
$doc = new DOMdocument();
#$doc->load($url);
$rss_array = array();
foreach($tags as $tag) {
if ($doc->getElementsByTagName($tag)) {
foreach($doc->getElementsByTagName($tag) AS $node) {
$items = array();
foreach($array AS $key => $values) {
$items[$key] = array();
foreach($values as $value) {
if ($itemsCheck = $node->getElementsByTagName($value)) {
for( $j=0 ; $j < $itemsCheck->length; $j++ ) {
if (($attribute = $itemsCheck->item($j)->nodeValue) != "") {
$items[$key][] = $attribute;
} else if ($attribute = $itemsCheck->item($j)->getAttribute('term')) {
$items[$key][] = $attribute;
} else if ($itemsCheck->item($j)->getAttribute('rel') == 'alternate') {
$items[$key][] = $itemsCheck->item($j)->getAttribute('href');
}
}
}
}
}
array_push($rss_array, $items);
}
}
}
return $rss_array;
}
$rss_item_tags = array('item', 'entry');
$rss_tags = array(
'title' => array('title'),
'description' => array('description', 'content', 'summary'),
'link' => array('link', 'feedburner'),
'category' => array('category')
);
$rssfeed = rss_to_array($rss_item_tags, $rss_tags, $url);
echo '<pre>';
print_r($rssfeed);
echo '</pre>';
exit;
?>

for RSS feeds, try using simplexml_load_file. It creates an object out of the XML and, as all RSS feeds are the same, then you can do something like:
$feed = simplexml_load_file(your_rss_url_here);
for($i=0; $i < 10; $i++){
// this is assuming there are 10 pieces of content for each RSS you're loading
$link = $feed->channel->item[$i]->link;
// do each for pubdate, author, description, title, etc.
}
