Do you have the same number of "vertex" entries for each "facet" entry? So could each "facet" be converted to a 4 x 3 numeric array?

If test.txt is your txt file, the following code will create a cell C whose cell contains your data ( all of it ). You can iterate along the cell and retrieve the data you need/want.
fid=fopen('test.txt');
C=textscan(fid,'%s');

fid=fopen('test.txt');
C=textscan(fid,'%s%s%s%s%s%s%s%s','delimiter','\n'); % read each line in string format
fclose(fid)
data1 = char(C{1,2});
data1 = textscan(data1,'%s%s%f%f%f');
data1 = data1(3:5);
for n = 1:3
num_data1(n) = data1{n};
end
num_data = zeros(3,3);
for k =4:6
data= char(C{1,k});
data = textscan(data,'%s%f%f%f%f');
data = data(2:4);
for n = 1:3
num_data(k-3,n) = data{n};
end
end
