[Zope] XML document error

12 Jan 2003

      Hi all
I was trying to create an XML Document as  Specified in the Zope Book .
## Script (Python) "query"
        ##
        import string
        # get the XML Document, must use getattr since
        # the id is not a legal Python identifier
        doc=getattr(context, 'addressbook.xml')

        # get the document element
        book=doc.documentElement

        # count items, assuming all children are items
        print "Number of items", len(book.childNodes)

        # get names of items
        names=[]
        for item in book.childNodes:
            # assumes first child is name
            name=item.firstChild
            # assumes name has one child which is a text node
            names.append(name.firstChild.nodeValue)
        print "Names ", string.join(names, ",")
        return printed

The error thrown is :-
Error Type: AttributeError
Error Value: documentElement

Could you please tell me where I have gone wrong.Is there some eror in the
way I am handling the getattr()  I have used.
Also could you please tell me where I could find details of where the
different functions or methods available in a defined python object and how
it can be used in Zope.Thanks for all help in advance.

Thanks and Best Regards
John Kunchandy
