How to check multiple lines?

Hi everyone.

I have problem in checking lines with words i need to find in file .txt.

This is the function that I found out:

function B=Check
B=struct('Day','','Quantity','');
%Read file
filename='log.txt';
id=fopen(filename,'r');
data=fgetl(id);
%Close file
fclose(id);
ind=strfind(data,'Priting Done');
B.Day=data(1:9);
B.Quantity=data(70:end);
end

But this function can only check one line. I don't know how to check multiple lines.

Please help me.

ind=strfind(data,'Priting Done');

You do not use the output of ind . As far as your function is concerned, you might as well not have bothered doing the comparison. You should be doing something different there.

data=fgetl(id);

That only reads one line. If you want to use fgetl() you should be looping.

Hint: fileread() and regexp()
