If I understand this right you mean selection with the mouse, something you do before the clipboard "Copy" operation. The problem is: such selection does not select any certain node. It selects a fragment of the document in its rendered form, not DOM; such selection goes across the DOM nodes of different levels. For example, it can select part of paragraph, several nested tables with images and a part of anchor. I don't think the whole idea of such selection reflects the DOM structure or can be applicable to it.

Oh yes, you are right. So let's change the question; Getting the DOM node of the htmlNode that the mouse is over it, or is clicking on it. When a mouse is pointing somewhere in the web page, it is exactly on 1 html element (e.g. Text, or link or image...) so I think in this situation we can get the DOM node.

Actually there is a program that it does what I exactly want. It's "Visual Web Ripper" and you can download a trial version of that from here:
Download Visual Web Ripper 2.76.5 (zip file, 6MB)

I need same thing. That would be a grate help. Thx ;).

Yes, this should be possible in principle, but if existing HTML rendering engines do not provide this functionality (they do not obliged to provide it as there are no standards that would require it), it would mean creating a custom HTML rendering engine. If you look at WebBrowser IE-based control you will see that click and mouse click events are not supported and selection of cursor position is not supported. This is what you would really need as a minimum, but not supported.

You can look at open source HTML rendering engines, look at source code and get some understanding of how to approach to the problem: http://en.wikipedia.org/wiki/Comparison_of_web_browser_engines.
