How can PHP developers effectively handle logic errors when working with XSLT transformations?

Logic errors in XSLT transformations can be effectively handled by thoroughly testing the XSLT stylesheet and the input XML data. PHP developers can use tools like XSLT processors such as Sablotron or Xalan to debug and troubleshoot any logic errors that may arise during the transformation process. Additionally, developers can enable error handling in their PHP code to catch and handle any exceptions that occur during the transformation. 

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

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

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

// Enable error handling
$proc->registerPHPFunctions();
$proc->registerPHPFunctions(array('handleErrors'));

// Transform the XML data
$result = $proc->transformToXML($xml);

// Handle any errors that occur during the transformation
function handleErrors($errno, $errstr) {
    echo "Error: $errstr";
}

// Output the transformed result
echo $result;
