Hi David,
No, thats not what I'm trying to do. I use the TTW editor interface, which
whilst it isn't quite as complex is, I find to be a lot nearer what my
customers seem to like! It does stuff like highlighting formatting.
What I'm trying to do is nearer to this
http://javascript.about.com/library/blhilite.htm where the highlighting is
done within the actual browser via css - i.e. there is no difference between
the content on the page before or after the highlighting has occured (as
looking atthe page source).
It seems to do this via .innerHTML and a <span>
I can pretty much see how it works, or should work, but I want it to use
just the text content of the iframe, and have no access to the main page
body at all.
Plus it needs the ability to highlight a pseudo tag which is used to embed
inclusion objects - like locations of .pdf files, images, media etc based
upon an incoming URL variable.

Essentially it gets triggered as part of the deletion impact protocol,
showing a user who is about to delete an inclusion object where it occurs
within the page's content.

All good fun! :-)
