Script to periodically check if a class has opened

Script to periodically check if a class has opened

Would anyone be able to help me generate a script which can either
periodically generate a search using the class search function
(website:SBCC Class - Lookup Search CRN: 36444) or look-up the correct
value from the Java/SQL (Not sure what they are using, sorry) table which
data is populated from?
Then based on the results of the search, I would to know whether or not
the class is CLOSED, OPEN, or WAITLISTED based on the result, and be
notified if the class is OPEN. Or if this is not possible I would be
interested in knowing why?
Again, any response is appreciated! Thanks.
