Word/DOCX-Eport: Applying python-docx

[drfho]

Traditionally ZMS uses the XML-represenation of it's content for (XSL-based) transforming it into 3rd-party formats like Word-XML. Instead using XSL (and its efforts with debugging) a direct, pythonic objekt transformation by the python-docx-library may be more practical especially with complex content-models . python-docx is a Python library for creating and updating Microsoft Word (.docx) files:

The evaluation notebook of 1e726cd in #288 contains some code- snippets to create a word file interacting directly with ZODB.

The notebook code is quite minimalistic to get objects attribute values by the rest_api public functions. @zmsdev: But template based content aggregration will result in "AttributeError: REQUEST" due to ZMSObject.isVisible(self, REQUEST) and its call of self.isActive(REQUEST), Line 502:

ZMS/Products/zms/zmsobject.py

Lines 496 to 504 in f12ccd8

	def isVisible(self, REQUEST):
	REQUEST = standard.nvl(REQUEST, self.REQUEST)
	lang = standard.nvl(REQUEST.get('lang'), self.getPrimaryLanguage())
	visible = True
	visible = visible and self.isTranslated(lang, REQUEST) # Object is translated.
	visible = visible and self.isCommitted(REQUEST) # Object has been committed.
	visible = visible and self.isActive(REQUEST) # Object is active.
	visible = visible and not '/'.join(self.getPhysicalPath()+('',)).startswith('/'.join(self.getTrashcan().getPhysicalPath()+('',))) # Object is not in trashcan.
	return visible

The function ObjAttrs.isActive() calls self.getType() and this will break, Line 551;
