Firstly I am a beginner with Chromium Embedded Framework. Ican browse an webpage through the following code. Now I want to access an webpage as a Document. My target is that after browsing an webpage I want a table or high chart represented in that page and as well as all the css used in that webpage. Please help me and tell me how can I access this page as Document then I can traverse the whole page using HTMLElment, HtmlCOllection property.

Is there any suggestion for myself?
