Translate MTGO prices (online page to txt file, every hour)

I need a small program that syncs every 1 - 2 hours with a website. The program must collect data from a website and write / translate this to a txt file on my computer. The data on the website looks like a text: for example: Pernicious Deed [AP] 17.3 19.6 ******[1] *****1] The following example line must be translated to a text file using the following format: AP;Pernicious Deed;19,6(minus 3%);19,6(minus 3%);17.3(minus 3,5%);17.3(minus 3,5%) Only text with value over 3 must be used. The textfile must updated every 2 hours.
