W3C HTML Validator
==================

[](#w3c-html-validator)

This is a PHP library to validate HTML using the W3C HTML Validator API (non-official). It includes a checkstyle.xml formatter, which can be used in continuous integration systems.

Installation
------------

[](#installation)

Install with [composer](https://getcomposer.org/):

```
php composer.phar require-dev micheh/w3c-validator:0.*
```

Usage
-----

[](#usage)

Run the `w3c-validator.php` file in the `bin` directory and provide a url or path to the HTML file, which should be validated with the W3C Validator. If a url is provided, it will grab the html locally and submit it to the validator, which enables you to validate a local page as well. The script will exit with error code 0 if no errors or warnings are found, and exit code 1 if there is at least one error and/or warning.

To create a checkstyle.xml file with the violations, provide the `--report-checkstyle=` flag and set the path where the xml file should be saved.

```
php bin/w3c-validator.php --report-checkstyle=artifacts/checkstyle.xml http://localhost/project1
```
