Reading a text file, skip the intermediate text lines and store the numeric numbers

Hello,

I have a text file which consists several lines of text followed by several line of numbers and so on. I want to skip the text lines and store the lines with numeric data in a matrix. How can I do that?

Text line 1..........

Text line 2.........

Text line 3............

------------------

1 0.233

Text line 1..........

Text line 2.........

Text line 3............

----------------

2 0.123

3 0.234

4 0.345

Text line 1..........

Text line 2.........

Text line 3............

----------------

8 0.346

9 0.123

10 0.222

11 0.223

......

......

and so on

I just want to store the lines that start with numeric number and ignore all the intermediate text lines and the lines of symbol (-------).

fid = fopen('abc.txt');
tline = fgetl(fid);
storedData ={};
while ischar(tline)
    if isstrprop(strtrim(tline(1)),'digit')
    disp(tline)
    storedData{end+1,1}= tline;
    end
    tline = fgetl(fid);
end
fclose(fid);
storedData

storedData =

8×1 cell array

{'1 0.233' }

{'2 0.123' }

{'3 0.234' }

{'4 0.345' }

{'8 0.346' }

{'9 0.123' }

{'10 0.222'}

{'11 0.223'}
