[jQuery] Problem with SVG/XML and Jquery ???

Hello,   
  
        I tried desperately to make the jquery with the SVG code
        but does that seem not to function... is it that someone 
        to an idea?  
        or of the examples that function ? 
                 thank you for your help 
        (I use Firefox and adobe plugin svg)

================================================================
The code doesn't function below
