I'd suggest that, rather than trying all this, you use the ParsedXML 
product from Infrae...

Re: [Zope] using DOM from within Zope

2005-05-25 Thread Dennis Allison 

A common approach is to isolate the functionality that uses the module(s) 
and put them in an Exernal Method or write a Product that incorporates 
them.  These approaches give much more freedom than Python Scripts which 
are given limited access because of security issues.

Example:

from Products.PythonScripts.Utility import allow_module
...
allow_module("xml")
allow_module("xml.dom")
allow_module("xml.dom.minidom")

Python Script "inside" Zope:

import xml.dom.minidom
xmlstring="texttextexthejhejhej"
domtree=xml.dom.minidom.parseString(xmlstring)
return domtree.toxml()



This is a FAQ: use external method or write a Zope product or look at 
TrustedExecutables
