Assuming you have booted the SVG DOM (see the Wiki if you don't know what I mean). They you can use getBBox on just about any SVG element and it will tell you the location of that element in it's local coordinate system. Then it's a trivial matter to calculate it's geometric center. However, this is occasionally not useful for mapping applications where the shape of the element may be such that the geometric center is outside of the filled region for the shape. Handling these cases automatically is far from trivial, so I am forced to leave you with a problem rather than a solution.
