is it possible to detect inline event handlers

[al_9x]

so as not to show the scriptless icon? I guess it's probably not worth walking the dom yourself, but gecko knows if there are events handlers registered, seems it should be possible to query it.

No, there's no sane way to do that. Furthermore, if JS is disabled on the page no event handler gets registered, so you'd be left with the DOM anyway.
