How do I loop this?
显示 更早的评论
Attached above is the log file.
Here is the code. can anyone help me how do I loop this in a manner that it can extract the needed data from the log? Thank you.
fileID = fopen('logfile (1).txt', 'r');
data = textscan(fileID,'%s');
table = string(data{:});
k = 1;
fprintf("Host: %s\n", table(k,1));
fprintf("Username: %s\n", table(k+2,1));
fprintf("Time: %s %s", table(k+3,1)+table(k+4,1));
fprintf("\nRequest: %s %s %s \n", table(k+5,1)+table(k+6,1)+table(k+7,1));

I would suggest you try to parse this file line by line first to extract the data. Then you can try printing it in a form you need.
You also shouldn't name your variable table, as that might cause confusion with the table data type.

In case you try any funny business here as well: there is now an archive of your question (which includes your attachment).

fileread into a character vector. regexp with named tokens and the 'names' option to get back a struct array with the fields broken out.
After that either loop over the indices of the struct array, or else extract the struct fields into separate variables {data.Host} for example, and use compose to format the entries, strjoin to put a newline between the pieces, and fprintf the entire string at the same time.
There are also ways you could proceed using regexprep() that might be even easier.
