[sf-lug] can you suggest a docbook-friendly editor for ubuntu?

[Michael Shiloh]

i'm new to docbook and want to try using it for all my teaching material.

i know i can edit straight xml (i'm very comfortable with this) but i
like the idea of a wysiwyg editor of some kind so i can see what i'm 
doing on the fly.

suggestions?

i'm told i can do this with libreoffice but i haven't quite worked out 
the process. i presume i need to save the file as an xml file but i 
don't see a docbook specific "save as" option.

suggestions welcome.
