How to place values in vectors from a text file

Hi,

I'm very new to Matlab, and have to find in a text some variables to store in separate vectors (a,b,c,d) to then plot and manage these data.

The input text looks like:

timestamp|tag|12 34 56 45|

timestamp|othertag|value|

timestamp|othertag2|value2|

timestamp|othertagN|valueN|

timestamp|tag|12 34 56 48|

..."

My idea is to "look" for the tag I am looking at, grab the data between the || after the specified tag, and then store each coordinate in a n_ish position of the proper coordinate vector.

But I really don't know how to even start in that.

Any help would be much appreciated.

Thanks

T = readtable('Test.txt', 'ReadVariableNames', 0);
C = cellfun(@(x) sscanf(x, '%d').', T{ismember(T{:, 2}, 'tag'), end},...
    'un',0);
Wanted = cell2mat(C)
