= Objectify::Xml
* http://github.com/pangloss/objectify_xml
== DESCRIPTION:
Provides an easy to use DSL resembling ActiveRecord for defining objects
representing any XML document, including deeply nested ones. This project was
extracted from my ruby-picasa gem. You can find ruby-picasa at
http://github.com/pangloss/ruby_picasa or available as a gem.
The project also has significant (if not complete) Atom support.
== FEATURES:
* Capture and typecast standard attributes
* Define both has_one and has_many nested element 'associations'
* Significant (if not full) namespace support
* Cleanly ignore unknown attributes and namespaces
* Support documents that nest data unnecessarily without creating bogus
associated objects.
* Inheritable object definitions
== PROBLEMS:
* None known.
== SYNOPSIS:
The following are functioning early definitions for some of the objects used in
ruby-picasa in their entirety:
require 'objectify_xml'
require 'objectify_xml/atom'
module RubyPicasa
class PhotoUrl < Objectify::Xml::ElementParser
attr_accessor :url, :height, :width
end
class Album < Objectify::Xml::DocumentParser
attributes :id,
:published,
:updated,
:title,
:summary,
:rights,
:gphoto_id,
:name,
:access,
:numphotos,
:total_results,
:start_index,
:items_per_page,
:allow_downloads
has_many :links, Objectify::Atom::Link, 'link'
has_many :entries, :Photo, 'entry'
has_one :content, PhotoUrl, 'media:content'
has_many :thumbnails, PhotoUrl, 'media:thumbnail'
flatten 'media:group'
namespaces %w[openSearch gphoto media]
end
class Photo < Objectify::Xml::DocumentParser
attributes :id,
:published,
:updated,
:title,
:summary,
:gphoto_id,

end
end
