Create an algorithim/program that pulls data from a website

I need a program, script or algorithm that will go to a website that lists/maps locations and pulls all the US locations from that website. For instance, the website [login to view URL] , I would like to be able to have an automated process that inputs the US zip code, State into the search bar and compiles the results in a txt or excel file. I want the program or algorithm, not the results. Please let me know if you have any questions. I would want it to work on any locations website, but the sites I am most interested in are: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL]
