parse/all read http://your-url-here [
some [ ; to repeat parsing ...
to <i>
here: ; mark the current position
(for i 1 3 1 [remove here]) ; execute rebol code ...
:here ; return back into parse context marking from

I just hope it will work, it is quite some time I used such "complicated"
parse statements :-))
PS: and if you want to use just one line: write %my-site.html replace/all
read http://my-site.html "<i>" ""
REBOL rulezzz!!!
