What are some potential pitfalls to be aware of when modifying a PHP script to work with a specific RSS feed format?

When modifying a PHP script to work with a specific RSS feed format, some potential pitfalls to be aware of include ensuring that the script properly handles different XML structures, handles errors gracefully, and correctly parses the necessary data from the feed. It's important to thoroughly test the script with various RSS feeds to ensure compatibility. 

// Example PHP code snippet to modify a script to work with a specific RSS feed format

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

if ($rss) {
    // Process the feed items
    foreach ($rss->channel->item as $item) {
        // Access specific elements from the feed
        $title = $item->title;
        $link = $item->link;
        $description = $item->description;

        // Perform further processing or display the data
        echo "<a href='$link'>$title</a><br>";
        echo "$description<br><br>";
    }
} else {
    // Handle errors if the feed cannot be loaded
    echo "Error loading RSS feed.";
}
