I am trying to figure out the way to track the lineage of HTML elements (an <img> element, say), through WebKit. For example, let's say we ask WebKit to load page A, which then contains an iframe for page B, and the <img> element is contained inside this page B. Then I want to record this lineage (A->B-><img>).
Any recommendations for doing this quickly? I can see parent-child pointers in the DOM data structures and that's what I plan to piggy-back on, in the absence of expert opinions. Thanks!
