hi

you can use readlines :

readlines('file.txt')

[RAKESH KUMAR TOTA]

Please check the text fie which i uploaded. I know how to read the file but the problem is i have to edit the node data lines where . to be remove and also one line to be leaved after starting element data and also after element data one line to be leaved. All lines to be started from left allignemnt and there should be a gap of only one space between node and element data.

any help in this direction would be appreciated

You can get my readfile function from the FEX. If you are using R2017a or later, you can also get it through the AddOn-manager.

The readlines function was introduced in R2020b and will work similar to readfile (except it will read to a string instead of a cell array of char arrays).

data=readfile('https://www.mathworks.com/matlabcentral/answers/uploaded_files/486763/aba.txt');
if isempty(data{end}),data(end)=[];end %strip trailing empty line if the file ended with a newline
for n=1:numel(data)
    if ~strcmp(data{n}(1),'*')
        str=data{n};
        %trim leading/trailing whitespace
        str=strtrim(str);
        
        %trim internal double spaces
        removed_double_spaces=inf;
        while removed_double_spaces~=0
            length1=length(str);
            str=strrep(str,'  ',' ');
            length2=length(str);
            removed_double_spaces=length1-length2;
        end
        
        %store back to cell array
        data{n}=str;
    end
end
fprintf('%s\n',data{:})

And what do you want the resulting file to be? Both readfile and readlines will work on the file you uploaded.

[RAKESH KUMAR TOTA]

Please check the allignment of lines in the text file. I want to change the text file according to the above way. Please see the above line which i wrote in comment section and check it with the text file . There is variation. For example please see the 10th line of text fiel and line which i would like to in text fiel i posted. Thank you

ok

so my 2 cent suggestion to make that array looks nicer -

lines = readlines('aba.txt','WhitespaceRule','trim');

ll_out = strings; % init string array
for ci = 1:numel(lines)
    ll = lines(ci,:);        % current line
    if ~startsWith(ll,'*');  % check lines 10 to 20 - here we have to work things out
        lldk = strrep(ll,' ',''); % remove all (multiple) blanks inside the char array
        ll_out(ci,1) = strrep(lldk,',',', '); % put back one blank after the comma (if really needed)
    else % nothing to do except copy the original line
        ll_out(ci,1) = ll;
    end
end

% save it - and remove the double quote
writematrix(ll_out, 'test.txt',"QuoteStrings",0)
