skip repeated line in text file

I have a txt file with a repeated pattern as follows, (3 lines to be skipped, 4 lines information to be read, ...)

00-00:00:17.170 : Starting Dose with 1000 cycles

00-00:00:17.228 : Starting Pump motor.

00-00:00:17.328 : Stopping Motor

Dose Cycle = 1

Dosing Time (ms) = 5700

Start Pressure = 0.08

End Pressure = 0.00

00-00:00:17.170 : Starting Dose with 1000 cycles

00-00:00:17.228 : Starting Pump motor.

00-00:00:17.328 : Stopping Motor

Dose Cycle = 2

Dosing Time (ms) = 5800

Start Pressure = 0.98

End Pressure = 0.00

.

.

.

My current code only reads 1 block,

fid = fopen('nums1.txt');

for k = 1:3

tline = fgets(fid);

end

while ischar(tline)

C = textscan(fid, '%s %f', 'Delimiter','=');

tline = fgets(fid);

end

how can I repeat it for next blocks (I have about 400 blocks)? I want to get a results as this:

C{2} = 1

5700

0.08

0.00

2

5800

0.98

0.00

Does anyone have any suggestion?I'd appreciate that.

Following is a possible solution for your usecase:

fid = fopen('nums1.txt');

tline = fgets(fid);

counter=1

while ischar(tline)

if(mod(counter,7)>=4)

if(counter==4)

C = (textscan(tline, '%s %f', 'Delimiter','='));

else

C = [C ; textscan(tline, '%s %f', 'Delimiter','=')];

end

end

counter=counter+1;

tline = fgets(fid);

end

% C(:,2) will return a cell array containing the required result
