SAX LexicalHandler::comment issue
Is there a good reason why the SAX LexicalHandler has a single comment() method rather than the more traditional approach of using startComment(), comment() and endComment()? Comments can be arbitrarily large, and it seems to fly in the face of the SAX streaming model to report a comment as a single event. The implication is that either the SAX Parser splits large comments on buffer boundaries and reports each chunk to the application [undesirable as it changes the structure of the document] or the SAX Parser will have to copy the comment chunks to an (arbitrarily large) internal buffer until the entire comment is read. I have tried testing the SAX interface to xerces with a large comment and it only called the comment() method once, suggesting that the comment was buffered internally. This is also the approach that we have adopted with the SAX interface to our C++ XML Toolkit, but the underlying native interface adopts the streaming approach What are other peoples thoughts? Is it worth proposing startComment()/comment()/endComment() for SAX x.x? Regards ~Rob -- Rob Lugt ElCel Technology http://www.elcel.com/
