remove whitespace and add character in txt

Question

Hello. I have a problem with Matlab code. What I want is that you delete all the blanks in a. Txt (example file below) and that one could add character ||||||||||||| to the end of each line.

Example txt:

*|V|0|0|0|t|0|1|1|4|11|T4|H01|||||||
P|40|0.01|10|1|1|0|40|1|1|1||1|*||0|0|0||
*|A1|A1|A7|A16|F|F|F|F|F|F|F||||||||
*|cod.  serv|area |codice |nome|tnom|tmin|tmax|pc|qc|cond|susc||||||||
*|Ciao questa rete ha 32 nodi

The matlab code should remove whitespace characters agguingere (||||||). txt in the output should be like this:

*|V|0|0|0|t|0|1|1|4|11|T4|H01|||||||||||||
P|40|0.01|10|1|1|0|40|1|1|1||1|*||0|0|0||||||||

The code that I thought is this the problem is that I can not rewrite the txt by mistake 'input cell .....'

        function [s]=correttore()
        clear all
        clc
        s = textread('Filein.txt','%s', 'delimiter', '\n', ...
                        'whitespace', '');  % Read

        s=regexprep(s,'[\s'']',''); % Eliminate white space
        assignin('base','s',s) % Save workspace

    % Don't work

    fid=fopen(...)  

    fprintf(fid,'Fileout.txt',s) % error 'cell input'

    % Don't work

%For add a carapther ||||||||| i think

 str='|||||||||||||||||' % but don't work
 str=str2mat(str) % but don't work
 str=mat2cell(str(1,:)) % but don't work
 s(:,2)=str % but don't work

Maybe is a 'cat' error? Any suggestion? Thanks in advance for the help.

Answer 1

not tested:

function [s]=correttore()
 fidin = fopen('Filein.txt','r'); % read-only, no danger
 fidout = fopen('Fileout.txt','w');
 while ~feof(fidin)
  s = getl(fidin); % char array
  s = regexprep(s,'[\s'']',''); % Eliminate white space - not tested
  fprintf(fidout,'%s\n',[s,'|||||||||||||||||']);
end
fclose(fidin);
fclose(fidout);

Answer 2

I have another question, in the txt. This text file is output to an old program done in C or Fortlan. sometimes the comments marked with * | not appear and there are only white lines. The file example should exemplify:

The data are divided into 'packages' distinct from the first letter (PNLS). Each package must have at least two dedicated lines (* |) which is then read as a comment. The white lines between different letters are filled with character * |. The lines between various letters that do not begin with * | to be added. The white lines and characters 'random' between identical letters are removed.

Perhaps it is more clear in the example files. It is very hard to implement the logic that should do what, I'm bad in parse data.
