How can one troubleshoot and debug XML parsing issues in PHP scripts effectively?

To troubleshoot and debug XML parsing issues in PHP scripts effectively, one can start by checking for syntax errors in the XML file, ensuring that the file is well-formed and valid. Additionally, one can use PHP functions like simplexml_load_file() or xml_parse() to parse the XML data and handle any errors that may occur during parsing. 

$xmlFile = 'example.xml';

// Check if the XML file exists
if (file_exists($xmlFile)) {
    // Attempt to load the XML file
    $xml = simplexml_load_file($xmlFile);

    // Check if XML parsing was successful
    if ($xml) {
        // Process the XML data
        foreach ($xml->children() as $child) {
            // Do something with each child element
            echo $child->getName() . ": " . $child . "<br>";
        }
    } else {
        // Handle XML parsing errors
        echo "Error parsing XML file.";
    }
} else {
    // Handle file not found error
    echo "XML file not found.";
}
