[Greasemonkey] reading document tree of iframe

[James Cowan]

thanks for the replies. I will take a look at the dojo solution.

There are a few things I do not understand about greasemonkey.

Assuming a greasemonkey script runs on all pages (includes *), does it run 
before or after the page is loaded?

Can a script within a normal web page call a greasemonkey script or vice 
versa? I guess a normal script can only call the window.GM_* functions but 
not functions defined in a gm script. Can a gm script call a function 
defined in a normal web page?

Or, if you do it using the same script (set to listen to both URL:s,
and differentiating on which location was loaded to run either branch
of the script), you could abuse GM_setValue and GM_getValue to
establish an elaborate communication protocol between the two frames
and GM script environments, aided by a polling setTimeout loop to pass
and listen to values between the two branches.

*Very* awkward, but doable, in a proof-of-concept kind of way.
