[Zope] Can I store structured text in a relational DB?

[nwingfield at dixon-hughes.com]

I am maintaining a content management site that uses a very user-unfriendly
rich text / html editor that allows users to format their content.  The
generated html is saved off in PostgreSQL and retrieved when the
corresponding page is requested.  The client is quite frustrated with this
editor because it causes them so much grief.  Is it possible to save
structured text to the database instead, and translate it upon retrieval
from the DB?  I (and the client as well) think this would be a wonderful
solution, but I don't know if it can done.
