Screen scrape using Java

I require a very simple application which scrap data from 7 different sites and create an xml output. The program should use an open source scrapping tool which called WebHarvest (you can find it in : [login to view URL]) What i need from you is a Web Harvest script files which creates variable contains the XML and a small java application which execute the script and print the XML (Example: [login to view URL]). There should not be any code in the java main except running the script and sending parameters value and output the XML (all the logic and the creation of the XML will reside in the scripts) There will be a total of 7 urls that we require web scraping. Here they are and the requirements. Each site would require its own script: [login to view URL] Search takes city, price range, bedrooms on its advanced link. [login to view URL] Search takes city, state, zip, price range, bedrooms [login to view URL] -> real estate Ebay is ebay. [login to view URL] Takes state, zip code & Price range [login to view URL] zip, state, city, listing type, price range, bedrooms [login to view URL] city, state, zip & price range [login to view URL] straight scrape, no search required Finally, the searches, when possible, should only return single family homes, not condos, apartments, rentals, or multi-units.
