php-validatore-fattura-elettronica is a PHP library that checks that an Italian electronic invoice XML file complies with the XML structure and the XSD schemas from the Agenzia delle Entrate.
Licence checked on 25/10/2026. Stars and last activity recorded on GitHub on the same date.
Overview
The library exposes a Validator class. Its assertValidXml method checks an electronic invoice XML: it throws one exception if the XML structure is wrong and another if the XML is valid but does not comply with the XSD. The getAllExceptions method instead returns the list of all errors found, empty if everything is correct.
It can also validate notification messages, using the XSD_MESSAGGI_LATEST constant. The XSDs come from the Agenzia delle Entrate website. The README warns that the package only works for Italian standards, and that email validation is deliberately more permissive: it is left to the user.
Highlights
- assertValidXml distinguishes two errors: wrong XML structure (InvalidXmlStructureException) and XML not complying with the XSD (InvalidXsdStructureComplianceException).
- getAllExceptions returns an array of all detected exceptions, empty if the document is valid.
- Notification validation is possible with Validator::XSD_MESSAGGI_LATEST.
- XSDs taken from the Agenzia delle Entrate website, judged more up to date than the other reference site cited (fatturapa.gov.it).
- The XSD’s email regular expression is replaced by a more permissive one, with the diff documented in the README.
Who it is for
For PHP developers who produce or receive Italian electronic invoices in XML and want to check them before sending or processing.
Installation
Install with Composer, then instantiate the Validator class and call assertValidXml or getAllExceptions with the XML content.
Commands
Read the project README before running these commands.
composer require slam/php-validatore-fattura-elettronicaPoints of attention
- The README warns that the package only works for Italian standards.
- Email validation is deliberately permissive and left to the user: the original XSD was modified on this point.
- The repository’s composer.json requires PHP ~8.4 or ~8.5 with the dom and libxml extensions; the README does not say so.
Can an agent use it?
No SKILL.md, AGENTS.md, CLAUDE.md, Cursor rules or MCP server found at the root or in the README. This is a PHP library to call from code.
