[Zope] XMLDocument create attributes problem

6 Oct 2000

      Hi,
I'm trying to make an external method create and set some attributes of nodes
in an XML document.  The following is a fragment of the code, and the error.  I
can't even get a valid attribute created, let alone set.  Does anyone have some
examples?

Please could you reply to me as well as the list,

regards
Matt

from Products.XMLDocument.XMLDocument import Document

def add(self, id, title):
    ob=Document()
    ob.title=title
    ob.id=id
    id=self._setObject(id, ob)

    log_node = ob.createElement('log')

    an_at = ob.createAttribute('attribute1')
