the short answer is to look at the XML library by Duncan
and in particular to have a look at xmlTreeParse or
xmlEventParse.  if you know what fields you want
to retain and will do this repetitively, we can
consider adding a function that saves those fields
to the annotate package to work in concert with the
genbank function.

writing handlers for the xml*Parse functions is
a little unintuitive at first but ultimately is
not too hard.
