SVG to HTML5 (canvas) through XSLT

Hi all!
I'm trying to learn XSLT beacuse I need to trasform an SVG file to Canvas element of HTML5.
The problem is that I know very little about XSLT, and so I hope here I can find a savior!

Starting from beginning..
I have a test.svg file like this:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="test_transform.xsl"?>
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" >
<rect x="12" y="25" />
<circle x="55" y="10" />
</svg>

The test_transform.xsl file, how it should be?
