Hi Marc <YourComment> It's quite true that you can have XML that does not require validation and that this is commonly done. An exception is the defaulting of the value of any attributes of elements in a DTD, which has been mentioned in another reply. You can construct a DOM without validation, but the next step ends up being a procedural implementation of picking apart the DOM document tree to construct whatever structure the application using DOM requires to interpret the document. I can parse: <book title="tale of 2 cities"> <chapter> <para>..<para> </chapter> <chapter> ... </chapter> ... </book> without a DTD. But if my application needs to get the information out of the DOM I need to write code to: Create a representation for Book consisting of a title and chapters and get book from DOM Create a representation for each Chapter and get Chapters from DOM Create a representation for each paragraph in a chapter and get paragraphs from DOM. Part of this is what is expressed in the DTD. Wouldn't it be better if a system were created that used the DTD on the receiving end to create the application representation instead of serializing it back into elements and constructing a new tree? </YourComment> <Reply> a) what do mean by " a representation" is it a rendition object? </Reply> Regards Didier PH Martin mailto:martind@n... http://www.netfolder.com xml-dev: A list for W3C XML Developers.
