Use matlab script to check symbol types in state chart

Question

I am writing a script that will open a simulink model and check for all the logical comparison data types. I have four comparisons in my model, two of which are logical operators, the other two are condition statements in the state chart shown below.

Using a script I can check the data types of the logical operators shown below but I'm having trouble finding documentation on how to check the symbol data types from the state chart.

load_system('comparison.slx');
RelOps = find_system('comparison','BlockType','RelationalOperator');
for j = 1:numel(RelOps)
   currRelOp = get_param(RelOps(j),'Operator');

   if strcmp(currRelOp,'==')
        currpc = get_param(RelOps(j),'PortConnectivity');
        currpc = currpc{1,1};
        srcblktype = get_param(currpc(2).SrcBlock,'BlockType');
        if strcmp(srcblktype,'Constant')
            srcblkdatatype = get_param(currpc(2).SrcBlock,'OutDataTypeStr');
        end
   end

I thought I would post this up on stack overflow while continuing my search. So far I have a script which can find all the variable names

compList = {'==' '!=' '<' '>' '<=' '>='};
charts = find(sfroot,'-isa','Stateflow.Chart');
st = find(charts(1),'-isa','Stateflow.Transition');

inputList = {};
for i = 1:numel(st)
    condStr = st(i).LabelString;
    if ~strcmp(condStr,'')
        if contains(condStr, compList)
            splitStr = split(condStr,compList);
            for j = 1:numel(splitStr)
                inputStr = char(splitStr(j));
                inputStr = erase(inputStr,{' ','[',']'});
                inputList = [inputList {inputStr}];
            end
        end
    end
    % For loop searching for data types
end
