[vtkusers] How to extract values of vtkpoint coordinates from vtkXMLPolyDataReader

[Chiranjib Sur]

Hi,
I want to extract the value of the XMl attributes (e.g. the coordinates of
the VTk points, PointData/Points/DataArray).

I am able to read the file using vtkXMLPolyDataReder and view it in
ParaView but I want to extract values individually.

How do I do that?

Thanks,
Chiranjib
