What are some best practices for debugging PHP code that involves XML parsing?

When debugging PHP code that involves XML parsing, it is important to check for syntax errors, ensure proper XML structure, and handle errors gracefully. Using tools like var_dump() or print_r() can help inspect variables and identify issues. Additionally, using try-catch blocks can help catch any exceptions that may occur during XML parsing.

try {
    $xml = simplexml_load_file('file.xml');
    
    // Check if XML was loaded successfully
    if($xml === false) {
        throw new Exception('Error loading XML file');
    }
    
    // Access XML elements
    foreach($xml->children() as $child) {
        // Process XML data
    }
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
