Why on earth would you want to do that? My reason was that I needed to draw SVG in Processing.js. So I took a simple flat SVG with filled polygons and converted it to JSON, which then is drawn by PJS. Here's the Python JSON extraction snippet.
#!/usr/bin/python
'''
Convert a simple svg to a bunch of javascript
arrays that can be drawn in code
stdout get the json
stderr print some information helpful in the js code
