$dom = new DomDocument; $dom->load('example.xml'); if ($dom->schemaValidate('example.xsd')) { echo 'example.xml is valid.'; } else { echo 'example.xml is invalid.'; }
$dom = new DomDocument; $dom->load('example.xml'); if (!$dom->schemaValidate('example.xsd')) { libxml_use_internal_errors(true); $errors = libxml_get_errors(); foreach ($errors as $error) { echo "Validation error: " . $error->message . "\n"; } libxml_clear_errors(); }In this example, we handle validation errors that occur during the validation process. If the XML document is invalid, we enable the use of internal XML error handling and get a list of all the validation errors returned by the validator. We then loop through the errors and display each error message. It is hard to determine the package library as the PHP `DomDocument` class is part of the core PHP library.
