Modify “Copy to SVG” script in Photoshop

Looking to modify the output of "Copy to SVG" to have relative positions to it's parent folder instead of absolute.

I  want to keep the image name to retain what it's named in PS and not what is currently in "xlink:href=" and have it save to a txt file.

Has anyone done this already or have a script that does something similar? I've attached the original script.

Current output:

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="2000" height="3500" viewBox="0 0 2000 3500">
