Hi, for a project I'm working on, I need to be able to send JSON-encoded objects on a network connection. I though that extending the xml_[io]archive classes could do the trick, given that JSON, just like xml, is based on representing an object by a collection of NVPs (name-value pairs). However, I was unable to find an explication on _how_ to extend that class, and I lost myself very quickly when I tried to follow the code in the source. Thus I'm wondering... First, should I actually modify xml_[io]archive or should I extend text_[io]archive by adding serialization of NVPs? If, as I think, the right way is to extend text_[io]archive, and more so if I should actually extend/modify xml_[io]archive, does anyone have suggestion on how to do that? Even better, does anyone have a JSON serializer I could use in a (*commercial*) project? Thanks a lot for your help -- Leo Cacciari Aliae nationes servitutem pati possunt.
