ValidatesXmlOf

Validates if a given string contains a valid xml and validates based on defined schema too.

Add this line to your application's Gemfile:

gem 'validates_xml_of'

And then execute:

$ bundle

Or install it yourself as:

$ gem install validates_xml_of

If you do not want to use xsd:

class Post < ActiveRecord::Base
  ...

  validates :content, xml: true

  ...
end

And if you want to use xsd, you will need to define an initializer to setup a path for your schemas:

ValidatesXmlOf.setup do |config|
  config.schema_paths = "lib/xsds"
end

After, you need to set your validation to specify what schema you are looking for:

class Post < ActiveRecord::Base
  ...
  # The schema must be in lib/xsds/Schema.xsd
  validates :content, xml: { schema: 'Schema' }
  ...
end

PS: Coming soon, I will implement a generator to create this initializer
