How can I filter out specific lines of text with textscan?

Hello, I have a large log file containing both words and numbers that I'm pulling data out of. The log file follows a similar format each time its generated but contains some occassional lines that can appear randomly throughout and always contain the same string of text. I imported the file into matlab using textscan to get each line into a separate array cell and to make searching and pulling out data easier I want to remove lines from the array/textscan that contain the same words I.E "Real time = " and "(Orbit) Eclipse Factor at". Is there a way to fiilter out lines containing either of these strings when I'm initially running textscan or will I need to create a loop that removes instances of each of these lines?

An example of what the file looks like:

(System) Subsystem:: compute_data_value: Voltage                     10
Real time = #/#/####  ##:##:##.#####
(System) Subsystem:: compute_data_value: Voltage2                    20
(System) Subsystem:: compute_data_value: NumCharging            8
(Orbit) Eclipse Factor at #/##/####   ##:##:##.###
(Orbit) Eclipse Factor at #/##/####   ##:##:##.###
(System) Subsystem:: compute_data_value: NumCharging2          4
Real time = #/#/####  ##:##:##.#####
Real time = #/#/####  ##:##:##.#####
Real time = #/#/####  ##:##:##.#####
(System) Subsystem:: compute_data_value: Current
(Orbit) Eclipse Factor at #/##/####   ##:##:##.###                      4
(System) Subsystem:: compute_data_value: Current2                    6

*Note that the Real Time.... and the (Orbit) Eclipse..... lines dont always appear in the same lines consistently between log files which messes up pulling data when I know Current2 is 4 lines below Voltage in other log files when the two strings I'm looking to remove are located in other places

Currently my setup looks like this:

filename = 'filename';
RT = fopen(filename);  
termRemove1 = '(Orbit) Eclipse Factor at';
termRemove2 = 'Real time = ';
TxtSearch = textscan(RT,'%s','delimiter','\n'); 
TR1 = find(contains(TxtSearch{1,1}, termRemove1));
TR2 = find(contains(TxtSearch{1,1}, termRemove2));

(At this point I was thinking of running a loop to delete the lines listed in TR1 and TR2 which are lines containing the strings to be removed, but there are over 9000 entries so I wanted to see if there was a way to remove the lines containg the string when I textscan the file, as well as the issue of the array lines being replaced with [ ] rather than removing them and lowering the total line count

Piece o' cake -- but use more recent tools than textscan will simplify coding somewhat...

filename = 'filename';
termsRemove=["(Orbit) Eclipse Factor at";"Real time = "];
text=readlines(f); 
text=text(~startsWith,text,termsRemove);

Thanks so much, this method worked perfect, I appreciate the help!
