Subject: [webkit-help] Get src and element from render object in dump tree








Dear everyone, 
    I am new to study Webkit for Chrome. In short, I used dump render tree for Google page: http://www.google.com : 
layer at (0,0) size 800x600 
  RenderView at (0,0) size 800x600 
layer at (0,0) size 800x371 
  RenderBlock {HTML} at (0,0) size 800x371 
    RenderBody {BODY} at (8,3) size 784x352 [bgcolor=#FFFFFF]

//......


I would like to know how could I inspect and access the element member in each of the render object? 
Like, how can I get the image object and the src from RenderImage? What functions I could use? 

Thank you very much.
