If you mean the XML output format, I don't think pyvtk will help you.
However, in the VTK sources there is a file called
Utilities/vtk2xml.py that you can use to convert an old style VTK file
to an XML file.  If you don't have the VTK sources handy grab the file
from here:

 http://www.ae.iitm.ac.in/~prabhu/software/code/mayavi/vtk2xml.py

It supports compressing the file also, so perhaps you can generate a
temporary file using pyvtk, convert it using vtk2xml and then use that
file.

cheers,
