here is my temp.pvb file:
<?xml version="1.0"?>
<VTKFile version="0.1" compressor="vtkZLibDataCompressor" byte_order="BigEndian">
<Collection>
<DataSet timestep="0" group="" part="0" file="temperature0.vtu" />
<DataSet timestep="1" group="" part="0" file="temperature1.vtu" />
<DataSet timestep="2" group="" part="0" file="temperature2.vtu" />
<DataSet timestep="3" group="" part="0" file="temperature3.vtu" />
<DataSet timestep="4" group="" part="0" file="temperature4.vtu" />
</Collection>
</VTKFile>
when I want open this pvb file on the Paraview GUI,it tell me choose one reader,and Try to select a lot of readers, but not display the pvb file correctly

the temperature.vtu file can display correctly, it shows as follows:
while reader should I pick?
The correct extension is pvd
and not pvb 
My file suffix is PVD, and the problem description text is wrong. the screenshot of Select

the reader, which indicates that the file name is temperature.pvd
OK.
In the Open file
dialog, can you select ParaView Data File (*.pvd)
as “files of type” entry ?
It looks like the type attribute is missing.
<VTKFile type="Collection" version="0.1" compressor="vtkZLibDataCompressor" byte_order="BigEndian">

the type is “Collection”
After select ParaView Data File (*.pvd)
as “files of type” entry when open the file, still pop up the choose reader window
Can you share a file then please ?
temperature0.vtu is the file you want
this is all about temperature.pvd
The VTKFile
tag requires a type="Collection"
attribute to be a valid pvd file. Making that change allows me to load the file.
temperature.pvd (507 Bytes)
