如何使用PHP从第三方网站解析格式错误的RSS源？

Question

I'm trying to parse RSS feeds from some medias. My script works for most of them. The problem is that I need to agregate all of them, eventhough they are malformed.

I don't manage to get the description of these two feeds. How could I proceed anyway ?

Here is my script :

<?php
function RSS_items ($url) {
    $i = 0;
    $doc = new DOMDocument();
    $doc->load($url);
    $channels = $doc->getElementsByTagName('channel');
    foreach($channels as $channel) {
        $items = $channel->getElementsByTagName('item');
        foreach($items as $item) {
            $i++;
            $y[$i]['title'] = $item->getElementsByTagName('title')->item(0)->firstChild->textContent;
            $y[$i]['link'] = $item->getElementsByTagName('link')->item(0)->firstChild->textContent;
            $y[$i]['updated'] = $item->getElementsByTagName('pubDate')->item(0)->firstChild->textContent;
            $y[$i]['description'] = $item->getElementsByTagName('description')->item(0)->firstChild->textContent;
        }
    }
    echo '<pre>';
    print_r ($y);
    echo '</pre>';
}
// the two malformed feeds
RSS_items ('http://www.lefigaro.fr/rss/figaro_actualites-a-la-une.xml');
RSS_items ('https://francais.rt.com/rss');
?>

Problem of your code is in useing firstChild property that select first child of element. But in target XML, description tag hasn't any childs that you want to select first of them. Remove it from code. The result should be like this

$item->getElementsByTagName('description')->item(0)->textContent;
