Ubl Validator Laravel Package

greenter/ubl-validator is a PHP library for validating XML documents against OASIS Universal Business Language (UBL) schemas. It reads the <cbc:UBLVersionID> from your document, locates the matching XSD file, and runs schemaValidate to confirm the XML is well-formed and compliant—ideal for SUNAT electronic invoicing in Peru.

use Greenter\Ubl\UblValidator;

$validator = new UblValidator();
echo $validator->isValid($xml) ? 'Success!!!' : $validator->getError();

• Automatic version detection from UBLVersionID
• Simple isValid() API with readable error messages
• Custom XSD directories via UblPathResolver
• Supports multiple UBL versions (2.1, 2.2, …)
• Installable with Composer from Packagist
