How can PHP developers effectively troubleshoot XSL-related errors in their code?

To effectively troubleshoot XSL-related errors in PHP code, developers can start by checking for syntax errors in their XSL stylesheet, ensuring that the XML data being transformed is valid, and using error handling techniques such as try-catch blocks to catch and handle any exceptions that may arise during the transformation process.

<?php
// Load the XML data
$xml = new DOMDocument();
$xml->load('data.xml');

// Load the XSL stylesheet
$xsl = new DOMDocument();
$xsl->load('stylesheet.xsl');

// Create a new XSLT processor
$proc = new XSLTProcessor();
$proc->importStylesheet($xsl);

// Perform the transformation
try {
    $result = $proc->transformToXML($xml);
    echo $result;
} catch (Exception $e) {
    echo 'An error occurred: ' . $e->getMessage();
}
?>
