read and write same file VTU

hi

i want to read and write VTU file and then visualize using Paraview.

from original VTU file i already done open and visualize it.

but i am trying to write in same script using

fprintf (B,....,... till end of input file)

the point that i have done want to update result from MATLAB (value E and F)

B = fopen('outp.vtu','w');

fprintf(B,'<VTKFile type="UnstructuredGrid" version="1.0" byte_order="LittleEndian" header_type="UInt64">');

fprintf(B,'\n <UnstructuredGrid>');

fprintf(B,'\n <Piece NumberOfPoints="72" NumberOfCells="25">');

fprintf(B,'\n </DataArray> \n </PointData> \n <CellData Scalars="pressure">');

fprintf(B,'\n <DataArray type="Float64" Name="pressure" format="ascii" RangeMin="50" RangeMax="80">');

fprintf(B,'\n %2.2f', E'); % update value from Matlab

fprintf(B,'\n </DataArray>');

fprintf(B,'\n <DataArray type="Float64" Name="temperature" format="ascii" RangeMin="200" RangeMax="380">');

fprintf(B,'\n %2.2f', F); % update value from Matlab

fprintf(B,'\n </DataArray> \n </CellData> \n <Points>');

fprintf(B,['\n 0 0 0 1 0 0 \n 2 0 0 3 0 0 \n 4 0 0 5 0 0 \n 5 1 0 4 1 0 \n 3 1 0 2 1 0' ...

i got error from Paraview below :

Error parsing XML in stream at line 113, column 3, byte index 1616: mismatched tag

Error parsing input file. ReadXMLInformation aborting.

this error come from connectivity grid, since i compare with original VTU file.

connectivity data all same?

any comments that what i have done?

thank you for help
