Hi Keith,
BrailleBlaster uses the xom package for handling xml. That is much
easier than using a sax parser directly. Look at the method walkTree in
DocumentManager. Keeping track of changes and reflecting them back to
the xml document is indeed a hard problem. I am thinking of using
customized StyledTextContent classes. See the various abstract classes
in the wordprocessing package.
I don't understand the error lmessage. Is there any other information?
There is certainly a lot to do in displaying and editing documents. I
think we will be using xsl stylesheets to format the display properly.
Thanks,
John
