Web Data Extraction

Web pages are built using text-based mark-up languages (HTML and XHTML), and frequently contain a wealth of useful data in text form. However, most web pages are designed for human end-users and not for ease of automated use. Because of this, tool kits that scrape web content were created. A web scraper is an API to extract data from a web site. We help you to create a kind of API which helps you to scrape data as per your need. We provide quality and affordable web Data Extraction application

Data Collection

Normally, data transfer between programs is accomplished using info structures suited for automated processing by computers, not people. Such interchange formats and protocols are typically rigidly structured, well-documented, easily parsed, and keep ambiguity to a minimum. Very often, these transmissions are not human-readable at all. That's why the key element that distinguishes data scraping from regular parsing is that the output being scraped was intended for display to an end-user.

Email Extractor

Scraping a Password Protected Website with cURL

One strategy for quickly populating a webstore with products is to write a scraping script to download data from your supplier’s website. This can be difficult if they require a password login to view product prices, descriptions, etc. There is, however, a solution.

1) Your first step is to obtain a login and password from your supplier or the website you will scrape. You probably already have this.

2) You need to figure out how they process your login information. You can do this by reading the POST variables sent by your browser. What is the easiest way to do this? Well, there is a simple Firefox extension that will do the trick. Check out a program called Tamper Data. Run this extension right before clicking Submit on your login form (it is under the Tools menu in Firefox if you installed it correctly). Then click “Start Tamper”. Now, submit your data.

You will get a screen that looks like this:

These are the results you get from Tamper Data when you login to the website. The POST variables are circled in red.

Now you know your POST variables. Let’s move on to the PHP code.

3) First, you need to write a script to log in to the website. I have done that for you. You just need to modify the URL and the post variables to work with the website that you are scraping. This script will only work if you have cURL installed. If cURL is not included in your web hosting package, get a new web host.
01    function login(){
02        $ch = curl_init();
03        curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/login.asp'); //login URL
04        curl_setopt ($ch, CURLOPT_POST, 1);
05        $postData='
06        txtUserName=brad
07        &txtPassword=fakepassword
08        &txthdbtn=Login
09        &imageField.x=27
10        &imageField.y=8';
11        curl_setopt ($ch, CURLOPT_POSTFIELDS, $postData);
12        curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
13        curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
14        $store = curl_exec ($ch);
15        return $ch;
16    }

This function will allow you to login to the website. The function returns the cURL session and you can use that later on to scrape the protected content. Note that the POST data is defined exactly the same as it was from the Tamper Data results. This is important. The website does not know whether you are a human browser or a computer program accessing its data.

4) Now that you have the cURL session, you need to do something with it. You would use this session the same as if you had ran
1    $ch=curl_init();

except now you have a cURL session that is logged in to the website. One example of you would use this session is to retrieve all of the data from a webpage. Have a look:
01    function downloadUrl($Url, $ch){
02        curl_setopt($ch, CURLOPT_URL, $Url);
03        curl_setopt($ch, CURLOPT_POST, 0);
04        curl_setopt($ch, CURLOPT_REFERER, "http://www.google.com/");
05        curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
06        curl_setopt($ch, CURLOPT_HEADER, 0);
07        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
08        curl_setopt($ch, CURLOPT_TIMEOUT, 10);
09        $output = curl_exec($ch);
10        return $output;
11    }

Note that this function does not close the cURL session. If you want to keep using your logged in session, you need to keep it open. Sample utilization of this function to download a specific URL and output it to the screen is:
1    $ch=login();
2    $html=downloadUrl('http://www.example.com/page1.asp', $ch);
3    echo $html;

The complete code looks like this:
view source
print?
01    $ch=login();
02    $html=downloadUrl('http://www.example.com/page1.asp', $ch);
03    echo $html;
04   
05    function downloadUrl($Url, $ch){
06        curl_setopt($ch, CURLOPT_URL, $Url);
07        curl_setopt($ch, CURLOPT_POST, 0);
08        curl_setopt($ch, CURLOPT_REFERER, "http://www.google.com/");
09        curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
10        curl_setopt($ch, CURLOPT_HEADER, 0);
11        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
12        curl_setopt($ch, CURLOPT_TIMEOUT, 10);
13        $output = curl_exec($ch);
14        return $output;
15    }
16   
17    function login(){
18        $ch = curl_init();
19        curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/login.asp'); //login URL
20        curl_setopt ($ch, CURLOPT_POST, 1);
21        $postData='
22        txtUserName=brad
23        &txtPassword=fakepassword
24        &txthdbtn=Login
25        &imageField.x=27
26        &imageField.y=8';
27        curl_setopt ($ch, CURLOPT_POSTFIELDS, $postData);
28        curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
29        curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
30        $store = curl_exec ($ch);
31        return $ch;
32    }

Data Mining vs Screen-Scraping :: Coupon World News

Data mining isn�t screen-scraping. I know that some people in the room may disagree with that statement, but they�re actually two almost completely different concepts.

In a nutshell, you might state it this way: screen-scraping allows you to get information, where data mining allows you to analyze information. That�s a pretty big simplification, so I�ll elaborate a bit.

The term "screen-scraping" comes from the old mainframe terminal days where people worked on computers with green and black screens containing only text. Screen-scraping was used to extract characters from the screens so that they could be analyzed. Fast-forwarding to the web world of today, screen-scraping now most commonly refers to extracting information from web sites. That is, computer programs can "crawl" or "spider" through web sites, pulling out data. People often do this to build things like comparison shopping engines, archive web pages, or simply download text to a spreadsheet so that it can be filtered and analyzed.

Data mining, on the other hand, is defined by Wikipedia as the "practice of automatically searching large stores of data for patterns." In other words, you already have the data, and you�re now analyzing it to learn useful things about it. Data mining often involves lots of complex algorithms based on statistical methods. It has nothing to do with how you got the data in the first place. In data mining you only care about analyzing what�s already there.

The difficulty is that people who don�t know the term "screen-scraping" will try Googling for anything that resembles it. We include a number of these terms on our web site to help such folks; for example, we created pages entitled Text Data Mining, Automated Data Collection, Web Site Data Extraction, and even Web Site Ripper (I suppose "scraping" is sort of like "ripping"). So it presents a bit of a problem�we don�t necessarily want to perpetuate a misconception (i.e., screen-scraping = data mining), but we also have to use terminology that people will actually use.

Todd Wilson is the owner of screen-scraper.com (http://www.screen-scraper.com/), a company which specializes in data extraction from web pages. While not scraping screens Todd is hard at work finishing up a doctoral degree in Instructional Psychology and Technology.
