Scrape Data From Wesbite and Dump into Spreadsheet

I am looking for a program or script that will scrape the price AND availability from a site such this: [login to view URL] If you select an entire month ( Say Sept 01 - Sept 30 ), click submit, and then view the source code I am interested in extracting three sets of information: 1) currency_x4_MaleXDorm_0____2012-09-01_code 2) currency_x4_MaleXDorm_0____2012-09-01_amount value="27.78" ( specifically all I want from this line is the dollar amount of "27.78" which should be labeled as "Price" 3) single_day_availability value="12" ( specifically what I want from this is the "12" which should be labeled as "# Available" This information should be exported into a spreadsheet readable format ( xls, csv, etc ) so that I can than work with the data. The preferred output should be in the following format: ROW 1: DATE ( in this example, Sept - but should be based on dates retrieved ) ROW 2: PRICE ROW 3: # AVAILABLE The dates should be able to be changed ( for instance if I want to run it for an entire month or a week or...) You can use whatever language you like - but I will want access to the source code. I can run a hosted script ( php, python, etc )
