How can debugging techniques be used to identify issues with parsing XML files in PHP?

When debugging issues with parsing XML files in PHP, one technique is to use error handling functions like libxml_get_errors() to identify any parsing errors. This function can provide detailed information about where the issue occurred in the XML file, helping to pinpoint the problem. Additionally, checking for well-formed XML syntax and ensuring proper encoding can help prevent parsing errors. 

// Load the XML file
$xml = simplexml_load_file('example.xml');

// Check for parsing errors
$errors = libxml_get_errors();
if (!empty($errors)) {
    foreach ($errors as $error) {
        echo "Parsing error: " . $error->message . " at line " . $error->line . "\n";
    }
}
