NAME

VS::RuleEngine::Writer::XML - Store VS::RuleEngine engine declarations as XML

SYNOPSIS

use VS::RuleEngine::Writer::XML;

my $xml = VS::RuleEngine::Writer::XML->as_xml($engine);

VS::RuleEngine::Loader::XML->to_file($engine, "my_engine.xml");

DESCRIPTION

This module provides a mean to write VS::RuleEngine engine declarations to XML.

INTERFACE

CLASS METHODS

as_xml ( ENGINE )

Returns a XML-representation of ENGINE

to_file ( ENGINE, PATH )

Creates a XML-representation of ENGINE and saves it at PATH.

XML Document structure

The structure of the XML created by this writer is described in "XML Document structure" in VS::RuleEngine::Loader::XML.

Arguments to entities (actions, inputs, hooks, outputs and rules) will be tested to see if it's a single hash reference and if so be written as such using the key as element name and the value as the elements text content.

However, if the implementing class of the entitiy implements the method process_xml_writers_args this will be called as a class method and is responsible for adding children to the element. The arguments to the method are the document as a XML::LibXML::Document-instance, the entity-element as XML::LibXML::Element-instance which to add children to and a list of the arguments encapsulated by VS::RuleEngine::TypeDecl-instance that represents the entity.
