Hello All,
I would like to check syntax errors in state flow state chart. As you see below, I have called state which is State_name, Inside this state I have different actions. If you see state_action2 = 0 missed by following semi colon(;) and state_action3 is not within state area.
How can I check state actions line by line and syntax errors by using m-script/commands?
Any help would be appreciated..

I give you a small code (not optimize and without check...). The code give the "txt" variable which is the text from a stateflow state and then I put each line in a cell of the cell array "Line".
nlChar = findstr(txt, 10);
Line{1,1} = txt(1:nlChar(1));
for i = 2:length(nlChar)
Line{i,1} = txt(nlChar(i-1)+1:nlChar(i));
end
Line{i+1,1} = txt(nlChar(i):end);
Then, when you have this cell aray, you just have to make your check on each cells.

Hello,
I can give you some command line which help you to access to the content of the stateflow chart.
% to catch the root of the stateflow chart, that yoy have selected by clicking on it
SfPath = gcb;
% to catch the stateflow object
SfObj = get_param(SfPath,'Object');
% to catch the chart object
ChartObj = SfObj.find('-isa','Stateflow.Chart');
% to catch all the StatesObj of the chart
StatesObj= ChartObj.find('-isa','Stateflow.State');
% To get the string in the FIRST chart (=> StatesObj(1))
StringInChart = get(StatesObj(1),'LabelString');
I hope it can help you.
(When I needed to access to stateflow data I found a lot of information in: Help > Stateflow > User's Guide > Using the API)

Hello Anthony,
Thanks for reply.. I have tried that and here is my code:
m=sfroot;
chartArray = m.find('-isa','Stateflow.Chart');
for i = 1:length(chartArray)
current_chart = chartArray(i);
stateArray = chartArray.find('-isa','Stateflow.State');
for j = 1 : length(stateArray)
current_state = stateArray(j);
state_actions = get(current_state(1),'LabelString');
end
end
Here problem is, state_actions returns all statements as single char. please have look on image.
but I want to read actions statements separately. so that I can check each action statement last char whether it ended with semi colon (;) or not and also I can find the length of each action statement.
so please let me know any idea on that?

Yes, you catch a char containing all the text.
Then you have to treat this char, to separate the line you can find the character "char(10)" (= new line) or "char(13)" (= carriage return).
Is it ok for you, or do you want a short example?
