How can i access one cell {1x1} to split/separate its contained value?

1 次查看(过去 30 天)
I have a .txt file , which contains data like follows
----------------Wed Aug 15 09:30:26 2018Wed Aug 15 09:30:26 2018Wed Aug 15 09:30:26 2018Wed Aug 15 09:30:26 2018----------------Wed Aug 15 09:30:28 2018Wed Aug 15 09:30:28 2018Wed Aug 15 09:30:28 2018Wed Aug 15 09:30:28 2018
I want to separate/split this data in following manner:
-------- (break)
-------- (break)
Wed Aug 15 09:30:26 2018 (break)
Wed Aug 15 09:30:26 2018 (break)
Wed Aug 15 09:30:26 2018(break)
Wed Aug 15 09:30:26 2018(break)
--------(break)
--------(break)
Wed Aug 15 09:30:28 2018(break)
Wed Aug 15 09:30:28 2018(break)
Wed Aug 15 09:30:28 2018(break)
Wed Aug 15 09:30:28 2018(break)
if I call/access that .txt file with fopen and fgets or importdata, all the data get stored in one cell {1x1}.How can i access this one cell to split/separate in shown manner?
P.S: Break means space or starting a new line

Here is a simple solution using regexprep:
>> str = fileread('test.txt');
>> regexprep(str,'(-{8}|\d{4})','$1\n')
ans = --------
--------

The test file is attached (you did not provide any sample file).

Thanks for the answer. One more thing, Its still in one cell {1x1} while i want to have the separated data in new cell or stored in one new matrix. So for your test.txt file it should make 1x12 cell/matrix. Thanks

@Ahmad Riaz Nayer: your original question indicated that you wanted line breaks, so that is what I inserted into the string. If you want to split the string into multiple strings, then try regexp:
>> str = fileread('test.txt');
>> C = regexp(str,'(-{8}|[\w :]+?\d{4})','match');
>> C{:}
ans = --------
ans = --------
ans = Wed Aug 15 09:30:26 2018
ans = Wed Aug 15 09:30:26 2018
ans = Wed Aug 15 09:30:26 2018
ans = Wed Aug 15 09:30:26 2018
ans = --------
ans = --------
ans = Wed Aug 15 09:30:28 2018
ans = Wed Aug 15 09:30:28 2018
ans = Wed Aug 15 09:30:28 2018
ans = Wed Aug 15 09:30:28 2018
