RSS affiliate iTunes php parser - php

Question

I tried to create a PHP script in order to extract all the data but this is not working. I tried to get the im:price and other attributes but I don't know how to get them.
Can anyone help me correct my script?
<?php
$rss = new DOMDocument();
$rss->load('https://itunes.apple.com/fr/rss/topfreeapplications/limit=25/xml');
$feed = array();
foreach ($rss->getElementsByTagName('entry') as $node) {
$item = array (
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
'price' => $node->getElementsByTagName('im')->item(0)->getAttribute('price')
'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
);
array_push($feed, $item);
}
$limit = 5;
for($x=0;$x<$limit;$x++) {
$title = str_replace(' & ', ' & ', $feed[$x]['title']);
$link = $feed[$x]['link'];
$description = $feed[$x]['desc'];
$date = date('l F d, Y', strtotime($feed[$x]['date']));
echo '<p><strong>'.$title.'</strong><br />';
echo '<small><em>Posted on '.$date.'</em></small></p>';
echo '<p> Price is '.$price.'</p>';
}
?>

In order to parse all of the im nodes you have to use namespaces like so.
$namespaces = $entry->getDocNamespaces(true);
$items = $entry->children($namespaces['im']);
Here is a sample to get you started:
<?php
$rss = "https://itunes.apple.com/fr/rss/topfreeapplications/limit=25/xml";
$xml = simplexml_load_file($rss);
foreach ($xml->entry as $entry){
$namespaces = $entry->getDocNamespaces(true);
$items = $entry->children($namespaces['im']);
$name = $items->name;
$summary = $entry->summary;
$price = $items->price;
$image = $items->image[1];
$rights = $entry->rights;
For all of the im nodes use $items->foo;. For all of the nodes without the im namespace use $entry->bar;
