[webkit-dev] Querying WebCore/KHTML directly about HTML elements?

Suppose I have an HTML page and I want to find out certain style attributes of a given HTML element, after all HTML tags and style attributes as well as embedded and linked CSS stylesheets have been applied (e.g. what font color the text in a certain paragraph will ultimately have). Can I use WebCore/KHTML to do this without having to rewrite a ton of code, and if so, how? (I posted this in webkitsdk-dev recently, but I realized that my question might be too low-level for that list and so decided to re-word and re-post it here. I apologize for the noise.) Thanks, Michael
