Path points- get anchor point width (variable width stroke)

Hello,

I'm new to Illustrator scripting, trying to do this in JavaScript.

I'd like to retrieve the "width" property for each anchor point in a path.

When I use the Width Tool, I can change the width for each anchor point along a path. That's easy. Now what I'd like to do is (in a script) loop through each point in a path shape, retrieve the XY coords for the point, but in addition- retrieve the stroke width for each anchor point.

I am assuming this is possible, because when I hover the Width Tool over an anchor point, I get a pop-up that shows me- very clearly, what the stroke width is at that point. It shows Side 1, Side 2, and Width.

Ultimately I am trying to export a text file. The text file format would be something like this:

Path_01 : X , Y , width

pt_1 : 118 , -116 , 1

pt_2 : 664 , -377 , 36

pt_3 : 528 , -585 , 1

Should be simple, and any help greatly appreciated!

Thanks
