Re: Xerces, XML Parsers and support for creating Documents.
thanks to Elena, Rahul Srivastava and Dare for the clarifications. They were very clear. Dare, We will continue to use Xerces because we are comfortable with it and also with javadoc.. Also for research, we almost always use unix/linux though everyone uses Windows both at home and also everyone has one machine at work with Windows.. Hopefully modifying code for serialization from one parser to the other should not be that difficult.. Note: Greatly wish .NET will include support for RELAX NG also.. cheers and regards - murali.
