US Patent 7844956 Object-oriented processing of markup

An application-specific client for object-oriented processing of markup includes a model object and a plurality of element objects. The model object is configured to respond to client requests including construct-element, accept-root-element, and accept-root-text. The element objects are configured to respond to client requests including accept-attribute, accept-element, and accept-text. Responses to requests contain application-specific processing as necessary. A driver generates client requests in response to processing of XML markup. An RSS client processes markup describing syndicated web content to HTML markup.
