There is a lot of data that is usually on the other side of an HTML. To a computer machine, a webpage is just a mixture of symbols, text characters, and white space. The actual thing we go to get on a web page is only content in a manner that is readable to us. A computer defines these elements as HTML tags. The factor which distinguishes the raw code from the data we see is the software, in this case, our browsers. Other websites such as scrapers may utilize this concept to scrape a website content and save it for later use.
In plain language, if you open an HTML document or a source file for a particular webpage, it would be possible to retrieve the content present on that specific website. This information would be on a flat landscape together with a lot of code. The whole process involves dealing with the content in an unstructured manner. However, it is possible to be able to organize this information in a structured way and retrieve useful parts from the entire code.
In most cases, scrapers do not perform their activity to achieve a string of HTML. There is usually an end benefit which everyone tries to reach. For instance, people who perform some internet marketing activities may need to include unique strings like command-f to get the information from a webpage. To complete this task on multiple pages, you may need assistance and not just the human capabilities. Website scrapers are these bots which can scrape a website with over a million pages in a matter of hours. The entire process requires a simple program-minded approach. With some programming languages like Python, users can code some crawlers which can scrape a website data and dump it on a particular location.
Scrapping might be a risky procedure for some websites. There are a lot of concerns revolving around the legality of scraping. First of all, some people consider their data private and confidential. This phenomenon means that copyright issues, as well as leakage of exceptional content, could occur in the event of scrapping. In some cases, people download an entire website for using offline. For instance, in the recent past, there was a Craigslist case for a website called 3Taps. This site was scraping website content and republishing housing listings to the classified sections. They later settled with 3Taps paying $1,000,000 to their former sites.
BS is a set of tools (Python Language) such as a module or package. You can use Beautiful Soup to scrape a website from data pages on the web. It is possible to scrape a site and get the data in a structured form which matches your output. You can parse a URL and then set a specific pattern including our export format. In BS, you can export in a variety of formats such as XML. To get started, you need to install a decent version of BS and begin with a few Python basics. Programming knowledge is essential here.
