How to read the data from an animatedline type figure made by Matlab?

I have used animatedline to plot a figure, and when I tried the normal ways to read the data in the figure, like

h2 = openfig('2.fig','reuse'); % open figure
D2=get(gca,'Children'); %get the handle of the line object
XData2=get(D2,'XData'); %get the x data
YData2=get(D2,'YData'); %get the y data

this way is not suitable for an animatedline, so do you know the way to read the data from the animatedline?

I followed Walter Roberson's answer. In the end, this is how my code looks

fig = openfig('figure1.fig');
anim_lines=findobj('type','animatedline')
XDataArr=[]; YDataArr=[];
line_nr=3; % indicates a subplot number
for iloop=length(anim_lines(line_nr).SegmentContainer.Children):-1:1
    used_data=anim_lines(line_nr).SegmentContainer.Children(iloop).Head;
    if used_data==0
        XData=anim_lines(line_nr).SegmentContainer.Children(iloop).XData(1:end);
        YData=anim_lines(line_nr).SegmentContainer.Children(iloop).YData(1:end);
    else
        XData=anim_lines(line_nr).SegmentContainer.Children(iloop).XData(1: used_data);
        YData=anim_lines(line_nr).SegmentContainer.Children(iloop).YData(1: used_data);
    end
    XDataArr=[XDataArr XData];
    YDataArr=[YDataArr YData];
    
end
% now plot the extracted data in a seperate plot
figure
plot(XDataArr,YDataArr)

findobj('type', 'animatedline')

You will need to loop over each of those. For each one, access the hidden property SegmentContainer.Children. That will be an array of objects. Each of the Children has a Head property that tells you how much of the data is used. There is an XData and YData and ZData property. ZData will NOT be empty for 2D lines.

The outline is that each animatedline divides the data into a series of fixed length segments. Each segment contains part of the XData, YData, ZData, and how much of the segment is used is recorded in the Head property.

I did not investigate the case of maximum length where it has to drop items.
