[Zope] XMLWidgets question

[Ron Bickers]

The best way to handle this is to create a widget for nodes of name '#text',
with a render widget of the following:

  <dtml-var getNodeValue>

Change your <p> render method as you suggested:

  <p><dtml-var render_helper></p>

Then, as the <p> node is traversed, it will render all element nodes within
the <p> as well as spit out any paragraph content (nodes with nodename of
#text).

See my DocBookDocument product (and specifically the DocBookWidgets/xw__TEXT
widget) for an example of this.
http://www.zope.org/Members/rbickers/DocBookDocument

Note that if you want the <table> element to render the same way in any
context, you can delete the isNodeSupported() method.  It comes in handy if
you have mulitple widgets that handle the same <table> node in different
contexts.
