Pass selected html source to popup window

Hi,

I am writing a plugin that bypasses the dialog command. I am able to grab the selected text in the popup from the editor by using...

var FCK = window.opener.FCK;
var sSelected = FCK.EditorWindow.getSelection();

... but I would like to pass the html source of the selected text, not just the text itself... for example... if i'm passing in a link, i would like to pass the underlying href that is associated with the anchor tag.

Thanks in advance.
