Already you have the data in hand. YOur xdata and ydata will be a cell with your required data. Check the below demo code:

figure
hold on
for i = 1:5
    plot(rand(1,10));
end
h = gcf;
axesObjs = get(h, 'Children');  
dataObjs = get(axesObjs, 'Children');
objTypes = get(dataObjs, 'Type');
xdata = get(dataObjs, 'XData'); 
ydata = get(dataObjs, 'YData');
% extract data
for i = 1:numel(xdata)
    fprintf('%d line data\n',i) ;
    xdata{i}
    ydata{i}
end
