I have tried some more ways which you suggest. Copying _xmlplus to /zope/=
bin=20
does not work. Renaming it to xml in /zope/bin does not work. Putting=20
_xmlplus into /zope/lib/python did not work. Renaming it to xml in=20
/zope/lib/python does work. I test it by starting zope and seeing whether=
=20
ther are any error messages regarding parsedxml, xmlwidgets or silva. In =
all=20
cases i delete the .pyc and .pyo files before starting zope to test.
I can only use silva if the _xmlplus file is renamed to xml and placed in=
=20
/zope/lib/python.
