[vtkusers] How best to programmatically write VTK XML files

[Olumide]

Hi -

I'm a VTK newbie using VTK to inspect geometry produced by my custom 
application (note: I'm not using the VTK API or writing a VTK 
application, I'm just using VTK for "visual debugging"). I've already 
written a legacy VTK writer but now I'm interested in VTK's XML formats 
especially the PVD and VTU formats. I'd like to know if there are any 
tools for programmatically writing such XML files.

Thanks,
