How do I read the number of nodes from a ssc file?

I have a ssc file. The contents of the file is below.

component BSC019N02KS

nodes

drain = foundation.electrical.electrical; % drain

gate = foundation.electrical.electrical; % gate

source = foundation.electrical.electrical; % source

tj = foundation.electrical.electrical; % tj

tcase = foundation.electrical.electrical; % tcase

end

nodes(Access=protected, ExternalAccess=none)

d1 = foundation.electrical.electrical;

g = foundation.electrical.electrical;

s = foundation.electrical.electrical;

g1 = foundation.electrical.electrical;

s1 = foundation.electrical.electrical;

d2 = foundation.electrical.electrical;

t1 = foundation.electrical.electrical;

t2 = foundation.electrical.electrical;

t3 = foundation.electrical.electrical;

t4 = foundation.electrical.electrical;

end

In this case the number of nodes are 5 . (drain, gate, source, tj and tcase). How do I get the number of nodes with the help of a matlab code?

[Walter Roberson]

S = fileread('BSC019N02KS.ssc');
nodelines = regexp(regexp(S,'nodes.*?end','match','once'),'\r?\n','split');
if isempty(nodelines)
    numnodes = 0;
else
    numnodes = length(nodelines) - 2;
end
