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
