Hello Thomas,
Thank you for the reply.
The 'SVGSVGElement.getIntersectionList' method takes
'SVGRect' as a parameter.
If I want to get the svg elements of some
'complex-region'(Say a free-hand drawn shape)
how can I do that?
Thanks and Regards

Well the SVG DOM has methods to get the list of
elements that
intersect a rectangle
(SVGSVGElement.getIntersectionList). It
sounds like this is more or less what you want (I am
unsure if
you need to support intersection with a 'complex
shape'). In
any case you would want to use something like
getIntersectionList
to do an initial cull of the elements in the document.

If you want to go from GVT (the drawing tree) to
DOM (the
SVG Document) you can use the BridgeContext methods:
GraphicsNode getGraphicsNode(Element)
Element getElement(GraphicsNode)
