[vtkusers] How to write multiple vtkPolyData into on single XML file

[Peng (Patrick) Cheng]

hi all,

I have hundreds of vtkPolyData in a list need to be output to a XML 
file, and later on read back. each of them is a line with a points and a 
scalars. I was just wondering is it possible to write all these data 
into  one XML file with current vtkXMLWriter? or do I have to output one 
file for each vtkPolyData?
