Are there any best practices for handling XML RSS feeds in PHP to avoid displaying unnecessary information?

When handling XML RSS feeds in PHP, one common issue is displaying unnecessary information such as HTML tags or metadata. To avoid this, you can use PHP's SimpleXML extension to parse the XML feed and extract only the desired data fields. By accessing specific elements within the XML structure, you can filter out any unwanted information before displaying it on your website. 

<?php
// Load the XML RSS feed
$xml = simplexml_load_file('https://example.com/rss-feed.xml');

// Loop through each item in the feed and display only the title and description
foreach ($xml->channel->item as $item) {
    echo '<h2>' . $item->title . '</h2>';
    echo '<p>' . $item->description . '</p>';
}
?>
