VTK has been patched upstream to correctly handle AppendedData elements in .vtu files with the updated/patched libexpat1:
https://gitlab.kitware.com/vtk/vtk/-/commit/db8f9efca220c9d16a30958e179abae3379d0011 https://gitlab.kitware.com/vtk/vtk/-/issues/19258 This will need backporting to older VTK releases on ubuntu's where libexpat1's fixes have been backported, which if I'm reading the ubuntu package release dates correctly is Jammy(security, updates), Mantic (security, updates) and potentially Noble (release). ** Bug watch added: gitlab.kitware.com/vtk/vtk/-/issues #19258 https://gitlab.kitware.com/vtk/vtk/-/issues/19258 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to expat in Ubuntu. https://bugs.launchpad.net/bugs/2058415 Title: Reading binary data in paraview broken by libexpat1 update Status in dune-grid package in Ubuntu: New Status in expat package in Ubuntu: Confirmed Status in paraview package in Ubuntu: Confirmed Bug description: The recent update of libexpat1 to version 2.5.0-2ubuntu0.1 broke Paraview. In particular reading vtu files containing binary data fails since this update. When trying to open files that worked fine before, Paraview now reports a parsing error like this one: ERROR: In vtkXMLParser.cxx, line 376 vtkXMLDataParser (0x5b0ac36fc970): Error parsing XML in stream at line 21, column 0, byte index 1036: not well-formed (invalid token) ERROR: In vtkXMLReader.cxx, line 521 vtkXMLUnstructuredGridReader (0x5b0ac3d3b670): Error parsing input file. ReadXMLInformation aborting. The problem disappears when reverting libexpat1 to version 2.5.0-2.
