ActiveModel::Serializers::Xml

This gem provides XML serialization for your Active Model objects and Active Record models.

Add this line to your application's Gemfile:

gem 'activemodel-serializers-xml'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activemodel-serializers-xml

To use the ActiveModel::Serializers::Xml you only need to change from ActiveModel::Serialization to ActiveModel::Serializers::Xml.

class Person
  include ActiveModel::Serializers::Xml

  attr_accessor :name

  def attributes
    {'name' => nil}
  end
end

With the to_xml you have an XML representing the model.

person = Person.new
person.to_xml # => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<person>\n  <name nil=\"true\"/>\n</person>\n"
person.name = "Bob"
person.to_xml # => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<person>\n  <name>Bob</name>\n</person>\n"

From an XML string you define the attributes of the model. You need to have the attributes= method defined on your class:

class Person
  include ActiveModel::Serializers::Xml

  attr_accessor :name

  def attributes=(hash)
    hash.each do |key, value|
      send("#{key}=", value)
    end
  end

  def attributes
    {'name' => nil}
  end
end

Now it is possible to create an instance of person and set the attributes using from_xml.

xml = { name: 'Bob' }.to_xml
person = Person.new
person.from_xml(xml) # => #<Person:0x00000100c773f0 @name="Bob">
person.name          # => "Bob"

This gem also provides serialization to XML for Active Record.
