Scrapping google adwords

I want to have a tool to scrape google adwords from [login to view URL] site on particular keyword For example "loan" or any loan translation that works in your country. Ads are visible after browser renders html and all javascripts on page. And stored in div with ids = tads, rhs_block I want to get list of number of place, urls,descriptions. or at least content of those DIVS, i can parse them myself after. i tried to make it thought selenium RC, but failed myself, so I want freelancer community to help me with this task. It should work under linux (debian/ubuntu is what I use) and must be easily editable. I think content can be taken using xpath language, so it should be an easy challenge for those who familiar with similar tasks. waiting your bids, suggestions are highly welcome.
