So, if you start copying and pasting the information in your file, it will take a lot of time and you might be feed up to scrape the data but web data extraction technique can help you to get the data in couple of minutes.
As we all know that most of the website displays its content which we can viewed using web browser but they don’t give us the facility to have a copy of those data for usage. You might be having a doubt why we require to scrape the data from the website if we can simply copy the needed information from it. In this article I will be showing you the easy way to scrape data from website. Basically, this technique is use to extract the information the user requires from that Website and export those data into different format such as Excel, SQL.

I will be explaining about it in detail and will be showing you how to use web scraping tool to get your work done in couple of minutes.
Let myNumber = NSNumberFormatter().numberFromString(myFinalString)!.Do you know that you can scrape data from any website easily and conveniently? There are some of the users who are familiar with the term data scraping and how it works but for those who don’t know what actually is data scraping and how does it works, you don’t worry. Let myFinalString = myShortenedString.substringToIndex(advance(string1.startIndex, 4)) // deletes all but the first 4 chars of the right-hand part of the string Let myShortenedString = myString.substringFromIndex(advance(myString.startIndex, startIndex)) // gets the right-hand part of the string Let startIndex = advance(distance(comed.startIndex, starter), -6) // backs up the index from where the range was found Var range = myString.rangeOfString("per kWh") Var myString = something something from NSString(data: data!, encoding: NSUTF8StringEncoding)

Once I get past that, I can use the following code to clip out just the data I need. Print(NSString(data: data!, encoding: NSUTF8StringEncoding))īut while I can print it, I can't seem to get the NSString data into a Swift string. The code in my first post nicely prints these couple lines to the console, and the numerical result I need is in the printed output So the "page" I need to extract the data from is much smaller, just a couple lines of text. I've since learned that the data I need can be accessed by directly linking to a servlet in a browser, see here for instance. Well I've gotten a lot closer but I'm still struggling. PS: in the example of how to inject a script, they used "Wikipedia" as an example site, so you can search for that on the asciiwwdc2014 site to find sessions that used that term. In the end I was able to get a form listener installed, so when a user logged in I could determine the email address used. I don't know JavaScript so this was a real PITA. In brief, you use a WKWebView (and perhaps you can make it invisible or offscreen), you tell it to connect to a URL, at some point you add your own script, then when the page has loaded, you invoke your script, which posts back some data. In the end I froze the video (or slide) and did a screen print to access the otherwise unavailable source code. One the WWDC 2014 sessions covered this topic, I believe it was "Introducing the Modern WebKit API". This is all terribly complicated (for me it was), and daunting as there are few examples to go by. You script can call one of the existing scripts, and return a value to you in a "post back" message. If the web page has scripts, its possible for you to inject your own script into the downloaded page, then call it.
