Line 440 of Node.h
virtual RenderStyle* computedStyle();

This gives you renderStyle.  If you do position.computedStyle(), you'll
obtain CSSComputedStyleDeclaration.

A node could be anything, so you need to first check whether it's an HTML
element or not.  You can do so by calling node->isElementNode().

Once node->isElementNode() returned, true, you cast the node into Element
and call getAttribute there as in:
static_cast<Element*>(node)->getAttribute(qualifiedName)

*Please post the questions like this on webkit-help.*
