This library provides a pure-PHP implementation of the following standards:

• Canonical XML Version 1.0 (http://www.w3.org/TR/xml-c14n)
• Exclusive XML Canonicalization Version 1.0 (http://www.w3.org/TR/2002/REC-xml-exc-c14n-20020718/)

Consider using this library if you need XML canonicalization on the legacy PHP versions (PHP 5.1.x). If you work with PHP 5.2+, you already have libxml-based canonicalization functionality available as DOMNode::C14n().

PHP 5.1 as a target platform means we don't have access to nice features, like namespaces, lambdas or composer. Don't blame be if this code looks outdated to you. :)

Note that you can easily migrate from pure-PHP implementation to Lixml-based one when you upgrade your infrastructure by simply replacing Sisyphus_C14n_Legacy with Sisyphus_C14n_Libxml.

Runtime: PHP 5.1

Development: ant, phpunit, phpmd, phpcs, hhvm and hhvm-wrapper, phpcpd, phpdoc.

If your using PHP 5.2+ you won't need this package, but it's available as a composer package anyway.

composer install

$service = new Sisyphus_C14n_Legacy();

$service
    ->withComments(false)
    ->exclusive(true)
    ->query('//n1:element')
    ->namespaces(array('n1' => 'http://n1.example.com'))
    ->inclusiveNamespaces(array('n1'));

$outputString = $service->canonicalize($xmlDocument)
