It's a bit complicated unfortunately... pyxpcom will make it easier, but
isn't ready yet :/

First you need to get the DOM document from the embed:

nsCOMPtr<nsIWebBrowser> browser;
gtk_moz_embed_get_nsIWebBrowser (mozembed, getter_AddRefs(browser));
NS_ENSURE_TRUE (mWebBrowser, NS_ERROR_FAILURE);

nsresult rv;
rv = browser->GetContentDOMWindow (getter_AddRefs (mDOMWindow));
NS_ENSURE_SUCCESS (rv, rv);

nsCOMPtr<nsIDOMDocument> domDoc;
rv = mDOMWindow->GetDocument (getter_AddRefs (domDoc));
NS_ENSURE_SUCCESS (rv, rv);

Now you can QI the dom document to nsIDOMNode, nsIDOMElement etc, and
use the DOM functions on it.
