Hi
I've got a text document and i would like to organize the data so that i could insert it in a table(SQL)
The 1st line is the number of organizations, the 2nd is the name of the first organization, the 3rd is the number of countries and then the countries until the next organization.
Does anyone have a clue on how this can be done?
Thanks

Attaching the text file would help. (Use the ‘paperclip’ or ‘staple’ icon just to the left of the (?)Help button.)

To read your file as a matlab table
c = cell(0, 2);
fid = fopen('somefile.txt', 'rt'); %open file for reading in text mode
numorganisations = str2double(fgetl(fid));
for org = 1:numorganisations
orgname = fgetl(fid);
numcountries = str2double(fgetl(fid));
for country = 1:numcountries
countryname = fgetl(fid);
c(end+1, :) = {orgname, countryname};
end
end
fclose(fid);
t = cell2table(c, 'VariableNames', {'Organisation', 'Country'})

fid = fopen('organizacoes.txt');
line = fgets(fid); i = 1;
while line ~= -1
T{i} = line(1:end-2); % end-2 to get rid of LF CR
line = fgets(fid); i = i + 1;
end
fclose(fid)
i = 2;
organization = {};
country = {};
while i <= size(T, 2)
n = double(T{i+1}) - double('0');
organization(end+1:end+n) = {T{repmat(i, [1 n])}};
country(end+1:end+n) = {T{i+2:i+2+n-1}};
i = i + 2 + n; % next organization
end

Thorsten,
  1. it is better to open text file with 'rt', so matlab can deal properly with line endings on different platform. You only need to deal with '' on all platforms. '\r' is appended / removed automatically for you on Windows.
  2. If you're going to strip the line endings anyway, use fgetl instead of fgets as fgetl does it for you.
