XmlNuts is an library that allows for bidirectional mapping between Ruby objects and XML.

Released under the MIT license.

• Type awareness (extensible).

• XML namespaces support.

• Pluggable backends to work with different XML APIs (REXML implemented so far).

gem install pipa-xmlnuts --source http://gems.github.com

Please see an example below. See also XmlNuts::Nut, XmlNuts::Nut::ClassMethods

• Inheritance

• Mixins

• More mappings?

• More types?
