What common error handling techniques can be used in PHP to identify issues with XML parsing?

When parsing XML in PHP, common error handling techniques include using try-catch blocks to catch exceptions thrown during parsing, checking for errors using functions like libxml_get_errors(), and setting error handling options with libxml_use_internal_errors(). These techniques help identify issues such as malformed XML or invalid data structures during parsing. 

$xml = '<invalid_xml>';
libxml_use_internal_errors(true);

$doc = new DOMDocument();
$doc->loadXML($xml);

$errors = libxml_get_errors();
if (!empty($errors)) {
    foreach ($errors as $error) {
        echo "XML Parsing Error: {$error->message}\n";
    }
}

libxml_clear_errors();
