[Paraview] filter for xdmf-file

[Natalie Happenhofer]

Hi!
 
Since I´m working now with xdmf-files I need to make my filter work with it too ;-) 
I have noticed that a few filters which using vtk-functions work with the xdmf file as well, so I started off making my filter as a subclass of vtkDataSetAlgorithm. 
If the input is a rectilinear grid, I cast the input to it and it works fine, the key here is that I have the function vtkRectilinearGrid::GetDimensions(int data[3]).
I need something similar for my xdmf file, is there any function I can use to get the dimensions of my datafile? as the dimensions are specified in the .xmf as well as in the .h5 file, there must be something to get it.. (at least I hope so). 
 
thx for advice,
Natalie Happenhofer
