FYI depending on what you are trying to get out you can also 

get the htmltext of widget "browser"; set the htmltext of templateField(); put the text of templateField()

and see if that may serve in some use case.

    Something like autoit can probably be set up to automate things.  Set up an
    autoit script that does the scrape, then use os scheduling tools to run the
    script as often as you like.  I haven't done it in windows in a while, but
    I think "at" is deprecated.  Can't recall whats replaced it.
