Why do you have to copy the code from the impl class? DOMWriter seems to consist entirely of virtual functions, so you should be able to override writeNode() and handle your user data or call the inherited DOMWriter::writeNode(). Unfortunately, I think you will have to also override DOMImplementationLS in order to construct your DOMWriter, and override DOMImplementationRegistry in order to construct your DOMImplemenation LS.

First off, forgive me if this is not the proper forum for this question. I did not see a xerces-c-users list at xml.apache.org. I have a DOMDocument which contains DOMElements which have attached UserData using the setUserData() function. I want to be able to interrupt the writing of the DOMElement nodes when serializing using a DOMWriter so I can output specific stuff found in my UserData. I still want to be able to make use of the formatter used by the DOMWriter so I don't have to recreate all the smart stuff it does regarding transcoding, escaping, etc. I have been investigating this, and so far, it appears I have but one choice: implement a DOMNodeFilter that sends back DOMNodeFilter::FILTER_SKIP from its acceptNode() member function, and set it to the filter for an object based on DOMWriterImpl so I can make use of its formatter and other handy functions, and serialize the element node myself. Another thought was to override writeNode() itself, copy almost all the code from the DomWriterImpl class, and just modify the part that does element nodes. Am I going about this in too complicated a manner? Is there a simpler way to do it? Am I nuts? Does a bear poo in the woods? Etc...etc...etc...
