Answer 1

What you're referring to is commonly called 'screenscraping'. There are a variety of ways to do this in Java, however, I prefer HtmlUnit. While it was designed as a way to test web functionality, you can use it to hit a remote webpage, and parse it out.

I would recommend using a good error handling html parser like Tagsoup to extract from the HTML exactly what you're looking for.
