I m searching to build up a course, which collects data from 6 different websites and exhibiting information which changes dynamically.
To be able to develop such program I need a screen scraper utility which has the capacity to extract data concurrently from 6 different Web pages which the information changes in a high frequency.
Begin to see the link below to obtain a concept of the kind and also the dynamic way the information is displayed.
The data is displayed somewhat in a different way around the 6 web pages, however the concept is extremely similar.
Can anybody please advise what's the correct utility software which is fantastic for such purpose.
Ethically screen scraping could be a dubious practice - but you will find legitimate uses. Search Engines Like Google perform a type of scrape to have their results, for example.
Some sites will block utilities which make a lot of demands - the industry valid reason to request permission if you are planning to create many demands - as it might otherwise seem like a DoS attack and also the site may do something against you.
Everything aside for those who have the best use to see the items in a webpage (to ensure that you are able to process it in some manner) the code is rather trivial.
// Initialize the WebRequest. WebRequest myRequest = WebRequest.Create("http://www.contoso.com"); // Return the response. WebResponse myResponse = myRequest.GetResponse(); // Code to use the WebResponse goes here. // Close the response to free resources. myResponse.Close();
