A Complete Learning Path To Web Scraping (With All Major Tools)
The history of web scraping is very long; In 1989 the World Wide Web(WWW) was launched and after some years  World Wide Web Wanderer: The first Perl based web robot was created by Matthew Gray at MIT, the purpose of this web crawler is to measure the size of the World Wide Web. While the wanderer was the first web robot it was not actually been used in data scraping tasks because in 90’s we don’t have an abundance of information(data) but with time as the internet user grows and a wave of digitization came, Web scraping became more and more popular. We have covered many articles on web scraping and today we are going to discuss all the different web scraping tools, frameworks, and languages. How different industries use Web Scraping?Can a non-programmer do web scraping?Web scraping frameworks/software:SeleniumBeautifulSoupUrlLib & RequestMechanicalSoupPuppeteerCheerioGoutteScraping BeeParsehubDiffbotConclusion Let’s answer some of the most asked questions and doubts about web scraping and then we will begin with all the different tools and frameworks for web scraping as we already discussed the short definition and history of web scraping let’s move forward with Q&A. How different industries use Web Scraping? Web Scraping became a major part of the E-commerce, Travel, and Recruitment industries. Retail and E-commerce industries make all the marketing strategies, service offering, campaign, and customer services based on data available to them. The E-commerce industry uses web scraping to extract the data and use it to analyze their customer behaviour, sentiments, likes, and recommendations. Travel industries use web scraping to gather information like hotel reviews, prices, and analytics. Many travels, tourism, and hospitality industries use this data to build business intelligence. Recruitment agencies do the same as the number of job seekers is increasing so it’s hard to manually pick resumes and find specific skill set candidates, so Web scraping comes very handy for recruiters to pick the best guy according to requirements and job descriptions. Can a non-programmer do web scraping? Yes, we have done a couple of tutorials on web scraping where we discussed a non-coder approach to web scrapings like parsehub and Diffbot both provides a Graphical User Interface(GUI) and great documentation of usage guidelines for data extraction they are very easy to use and you can see the processing and outputs in realtime as the utility run. Web scraping frameworks/software: Selenium Selenium was originally developed by Jason Huggins in 2004 as an internal tool at ThoughtWorks(a global software consultancy firm). In Earlier days, It was mostly used for testing, but now it’s widely used for browser automation platforms and, of course, web scraping! Selenium is widely used with python language and it is one of the earliest and popular web scraping tools.It works with a chrome web browser.Can operate web browsers in headless mode(opts.headless =True).Selenium provides some of the easy and handy functions for finding elements by name, XPath, tag_name, css_selector, class_name, and partial_link_text.

It creates a parse tree from source code that can be used to structure data in a hierarchical and more readable manner BeautifulSoup can work with your favourite web parser to provide the best way to search, navigate, and modify the parse tree. Some of the features of BeautifulSoup are as follows: Extremely lenientParse pages the same way as a browser does.Can Style the Source code in hierarchical tree manner for easy understanding.Very fast.Support HTML and LXML parser.Can easily integrate with other frameworks as we used BeautifulSoup in many articles with urllib, selenium, and request module.Contains many inbuilt functions for filtering, structuring, searching, and many more.It comes with the most widely used programming languages i.e. Python. See implementation here Scrape Beautifully With Beautiful Soup In Python UrlLib & Request URllib is a python package that combines several modules to preprocess the URLs, in other words, it is a library used for HTTP requests using python language on URLs, now Urllib is used first before start scraping data from website using any module like selenium, BeautifulSoup, or mechanical soup. Selenium and other libraries don’t have any feature to request data from URL so we use request and Urllib for requesting data. some of the features of UrlLib library are as follows: Supports thread-safe connection.Connection pooling.Client-side verification using SSL/TLS verification.Multiple encoding support.Support for gzip and brotli encodingEasy method call like urllib.request() for open and read URL and urllib.error() for catching exception raised by urllib.request. Request is another open-source python library that makes HTTP request more humans friendly and simple to use than urllib as it is made on top of urllib library, it was developed around February 2011. Some of the features of the Request library are as follows: Support fully restful API, and it is easier to use and access.Provide POST/ GET functionality on URLs.It is used for Web API request purposes.Authentication module support.Handles cookies and sessions very firmly.Provide JSON decoder and Thread safety.Multiple files upload.Unicode response body..netrc support and SSL verificationInternational domains and URLs access capabilities.
