How can PHP developers effectively troubleshoot issues related to parsing and extracting data from XML files?

To effectively troubleshoot issues related to parsing and extracting data from XML files in PHP, developers can use built-in functions like simplexml_load_file() to load the XML file and navigate through its structure. They can also use XPath queries to extract specific data from the XML document. Additionally, error handling techniques such as try-catch blocks can help identify and address any parsing errors that may occur. 

try {
    $xml = simplexml_load_file('data.xml');
    
    // Extract data using XPath
    $results = $xml->xpath('//book[author="John Doe"]');
    
    foreach ($results as $book) {
        echo $book->title . "<br>";
    }
} catch (Exception $e) {
    echo "Error parsing XML: " . $e->getMessage();
}
