Abstract: The present invention provides a method of rendering document data compliant with an KM-based mark-up language, comprising the steps of: fetching the document data) parsing the document data into a document object model (DOM) representation so as to provide a tree structure, comprising nodes representative of the document data elements including tags and/or attributes; reconstructing the document object model (DOM) representation by replacing the nodes of pre-specified elements of said document data elements by one or more nodes comprising standard XML compliant elements having standard tags and attributes; rendering the document data with the reconstructed document object model (DOM) representation.
