How to get data from figures produced by errorbars?

I have a figure which was produced by using errorbars command. It plots the mean data and corresponding error bars.
Now I would like to obtain all data from this figure.
I can easily get the mean data by:
openfig(figName);
xData = get(get(gca, 'Children'), 'XData');
yData = get(get(gca, 'Children'), 'YData');
However, I still don't know how to obtain data about error bars.
May I get some advice on this?

%example data
X = 0:pi/10:pi;
Y = sin(X);
E = std(Y)*ones(size(X));
errorbar(X,Y,E)
%get data
xData = get(get(gca, 'Children'), 'XData');
yData = get(get(gca, 'Children'), 'YData');
uData = get(get(gca, 'Children'), 'UData');
%lets see if its equal
isequal(E',uData) %it is equal, same content
