Live Data (Pricing) Scrape & Insertion Of Relevant Returned Elements Into Originating Query Page/Session - open to bidding

. Travel portal - [login to view URL] 2. ( Demo User: testy | Pass: mytestpass ) 3. Want total checkout pricing of exact same hotel & search parameters performed by a [login to view URL] user to be parsed into query string via Java/Jquery with results returned to page in comparison display divs (to be coded). 4. Hotel Checkout and majority of booking path take place on external (white label) server of which we control headers, footers and CSS. We are able to execute Java and DOM functions. Front end of site is wp/php/mysql. 5. Only want results from Expedia, [login to view URL], [login to view URL], Hotwire.com. 2) The current requirement is to develop a Server version of the scraper. The expected features are as under:- a) The Products Table in the server database to be automatically populated by the scraper. The required fields are Product ID, Title, Price, Vendor, Stock Position, Payment Options, Delivery Time b) Easy extensibility (with some python coding) to add more sites in future. c) To meet the above, the scraper to be implemented as two modules. The "Scraper Module" and the "Parameter Module". d) The "Scraper Module" would do the actual scraping of multiple sites (based on parameters read from the Parameters Module), and also automatically populate the Products Table in the database server. For sites with content rendered in JavaScript, Scrapy to be used with Selenium for effective scraping. e) The "Parameters Module" would include a Form through which scrape parameters such as the primary URL, scraping rules for each field to be scraped, format of data to be extracted, and whether to use simple crawl (for sites without JavaScript) or complex crawl (for sites with content rendered in JavaScript). These parameters would be stored in a table, and accessed by the "Scraper Module" at run time. f) The scraped URLs (referred by the primary URL) to be saved in a Database Table with "processed flag", so that these can be skipped if scraping needs to be resumed after interruption. g) Primary URLs also to be saved with the date of last successful scraping, to enable scheduling of periodic repeat scrapings. h) While executing scraping, only those fields that have changed since last scrape are to be extracted and the original table entry for the product to be "updated", as required. In case of new products, the details to be "inserted" as a new row in the Products Table. i) Scrapy to be used with Selenium for effective scraping of sites with heavy JavaScript content. j) Performance must be adequate to enable scraping of the sites in order to generate the Products database Expected Skills: Web Scraping, Scrapy, Selenium, Python, Data Mining, Javascript, MySQL Budget: USD 200 to USD 300
