Some sample scripts for screen scraping

JeremyCothran

NWLON (tides)

• screen scrape the predicted water levels(lwpNWLONPredicted.pl) from a list of sites(Carocoops sample list of sites also attached as nwlon_stations.txt)

• screen scrape the actual water levels(lwpNWLONActual.pl) from a list of stations

• compute and update the difference for the collected values(NWLONDiff.pl)

Also attached a description of the postgres table(water_level.txt) this is running this against - note there is a unique index on the station and date time, so the initial process does an insert and the following processes do updates based on the same station and datetime.
