I will add a lot of tutorials (e.g. how build a list of Ruby books by scraping say amazon, b&n, [buy.com](http://buy.com) and putting the result together for price comparison etc.). and possibly some theory, too, so you could check it out. Unfortunately I have tons of other tasks right now so I am not progressing as fast as I would like, but if you can wait at most a few weeks, it will happen sooner or later for sure. I would be really happy for any feedback and constructive ideas on which new features to add etc. Peter \_\_ [http://www.rubyrailways.com](http://www.rubyrailways.com) ---

I am just planning to beef it up with some more theoretical stuff, as well as HPricot, (Fire)Watir and other ‘chapters’… > YES, I would like to have a GO! Please send me the URL/Instruction > directly… Cooool! Well, you will have to wait a few days at least… Until then, here is an example of what to expect in 0.1.0: ebay\_data = Scrubyt::Extractor define do #Navigate to our page fetch ‘[ebay.com](http://ebay.com)’ fill\_textfield ‘dell laptop’ submit click\_link ‘Laptops/Notebooks’ #Construct the scraper record do name “DELL LATITUDE C600 P3 1.0 LAPTOP NOTEBOOK 256MB 20GB HD” price “$192.50” do (value /\d+.\d\d/).ensure\_greater\_than 150 end shipping “$37.00” end.ensure\_presence\_of\_pattern(:price) next\_page “8 9 Next”, :limit =\> 5 end So, this extractor will automatically navigate to the page of interest (powered by Mechanize, later planning to add (Fire)Watir for javascript navigation or maybe even selenium). There, extract all records (specified by the example) which have a price, and this price is higher than 150. Once finished, navigate to the next 5 result pages and extract the records there too. what you get back in ‘ebay\_data’ may be used in various ways. Either calling different to\_xxx methods on it (for example to\_xml - planning to add to\_csv, to\_atom etc.) or like this: ebay\_data.record[3].price etc. This is but the top of the iceberg - I have tons of todo lists for the future releases :-). Also, the DSL can be very easily extended by anyone (with things like ‘ensure\_greater\_than’ - for example ‘ensure\_contains\_string’ etc.) so it is not a take-it-and-use-it thing but a rather flexible tool to do these kind of stuff. Stay tuned, Peter \_\_ [http://www.rubyrailways.com](http://www.rubyrailways.com)
