Convert SVG polygon to path

Question

I have a fairly large SVG file of administrative subdivisions that I need to work with in Raphael.JS (it has 600 polygons and weights 1.2 Mb).

Now, I need to convert

Answer 1

A clicky-bunty answer:

1. open the svg in inkscape vector graphics editor
2. select all objects (ctrl-a)
3. at the drop down menu point "path" select first entry "object to path" (shift-ctrl-c)
4. save the svg and check out the path properties

Might be not an appropriate answer (because with large files the program needs some time).
