Hi,
you'd better use the transform property of the SVG DOM elements.
Here is a little function to get the angle properly :

Objet: [svg-developers] Get first parameter of rotate function
Hello,
I just joined your SVG group. I'm working on a web application which is based
on SVG. I have a little problem concerning the rotate parameters of a text
element. I want to fetch the first parameter of a rotate function which
represents the rotation angle in degrees.
I use the jQuery SVG plugin of Keith Wood to use jQuery to interact with the
SVG canvas. To fetch the angle I use the indexOf and substring methods of
JavaScript. For instance:
currentFontRotation = currentId.attr('transform');
var bracket = currentFontRotation.indexOf('rotate(');
var comma = currentFontRotation.indexOf(',');
bracket = bracket +7;
currentFontRotationNumber = currentFontRotation.substring(bracket, comma );
The variable currentId represents the selected text element. Is there a more
clean way to get the angle. I think it's a pretty dirty method to use the
indexOf and substring methods in this case.
Thanks
