Hi,
Please, read this :

As you can see, Chromium uses several processes and the DOM lives in the "renderer" process.
This means that if your application needs to handle HTML elements then you will need to know how to send information between the renderer and the browser processes.
There are several demos showing how to do that like DOMVisitor demo and most of the demos inside the "JavaScript" directory.
Please, read the code comments in the JSExtension demo because it has detailed information about the JavaScript extensions used to send information from JavaScript to your Delphi code in the browser process.
