In this specific example, we will get the HTML content of a webpage and display it. For this, we first set the url; in this case, I’ve chosen the common sense media website . We then use the get() method to fetch the response object and extract the HTML portion using the content or text attribute. Beautifulsoup is a Python library used for web scraping. This powerful python tool can also be used to modify HTML webpages.
This example illustrates how easily we can parse web pages for product data and a few key features of beautifulsoup4. To fully understand HTML parsing let’s take a look at what makes HTML such a powerful data structure. Finally, to solidify all of this, we’ll take a look at a real-life example web scraping project and scrape job listing data from remotepython.com. As you can see, the .contents property returns the first child with his children. To get all elements separately, you should usefindChildren(). Tags with a for loop I get all the tags inside the div.
The Section Element
Fourth, instead of just printing out the “a” variable, we will strip it of empty spaces and then use the writerow() method to write it to the csv file. Beautiful soup is yet another excellent library in python which is being widely used to scrap web content from any webpage using python. To scrap the web content using python, beautiful soup is the best tool. We’ve also taken a look at some utility functions beautiful soup package offers like clean text extraction and HTML formatting – all of which come are very useful web scraping functionalities. Scraping beautiful soup is pretty straightforward forward however when scraping more difficult targets our scrapers could be blocked from retrieving the HTML data.
While this methodology isn’t great, it wouldn’t be that bad if they were the only ones that ever had to touch the code they write. In the following example, we’ll find the div element and get the inner of the div. This tutorial is mainly based on the tutorial Build a Web Scraper with Python in 5 Minutes by Natassha Selvaraj as well as the Beautiful Soup documentation.
Beautiful Soup Documentation¶
Cory lives in Kansas City and is active on Twitter as @housecor. Chillybin have built me two incredible sites and everything they do is first-class. You can start with a concept, and the team will help you take it to the next level, so you start off on the right foot, and can use your website to drive traffic and sales from Day 1. Projects are delivered on time and they explain things in simple to understand terms, which is the icing on the cake. Soup isn’t just an annoyance, it’s a problem that can negatively impact your website. Here at Chillybin, our developers take coding and building websites for our clients seriously.
Eventually, in your web development career, you’re going to come across certain developers who just don’t care. You can check outBeautifulsoup – How to get New Lightweight JetBrains Editor Draws VS Code Comparisons Visual Studio Magazine the children of a tagfor more examples for getting children of any element. Again, we can use the div class “quote” to retrieve the data about the authors.
Now of course it’s not a good practice even the things are working fine with this approach. So rendering unnecessary content is generally never a good idea in programming. Hence this wrapping div or this wrapping element approach is okay but not ideal. Or generally any wrapping element, a new problem arises, which is called div soup. This is because in React or in JSX in general, you can’t have more than one root JSX element. So if you return a value or if you store a value in a variable, that value must only be exactly one JSX element not two or three or four side by side adjacent elements.
- If contains a duplicate “id”, the document still works but we may not get the element that we need.
- This is because in React or in JSX in general, you can’t have more than one root JSX element.
- BeautifulSoup is one of the most popular libraries used in web scraping.
It’s that this output actually does those things fairly well, or at least as well as they intend to do them.

The footer element represents the “footer” section of a document or section. In many websites, the footer element will contain contact and copyright information, a brief “about” blurb, social media logos and links, etc. As we know in the HTML, “id” is unique to the entire document. If contains a duplicate “id”, the document still works but we may not get the element that we need. Often complex text structures are represented through multiple HTML nodes which can be difficult to extract.
Searching by CSS class¶
In this case, I’ve chosen the lxml parser, and so I will install it. If you have questions about Beautiful Soup, or run into problems,send mail to the discussion group. If your problem involves parsing an HTML document, be sure to mentionwhat the diagnose() function says about that document. We had a quick look at what are HTML structures and how can they be parsed using bs4’s find functions and dot notation as well as how to use CSS selectors using select functions. Above, we first use the find function to find the table itself.
In React, there is a solution to tackle this problem out of the box. There is a component available in React library called Fragment. We can access that component like React.Fragment or you can just import Fragment from React in the file. S which add no semantic meaning or structure to the page but are only there because of React’s/ JSX’ requirement. We can end up with a real DOM that’s being rendered where you have many nested React Components and all those Components for various reasons need wrapping divs or have wrapping Components. And you have all these unnecessary divs being rendered into real DOM even though they’re only there because of this requirement or this limitation of JSX that we have talked about earlier.

It also comes with utility functions like visual formatting and parse tree cleanup. Web scraping is a technique used to select and extract specific content from websites. For instance, when we want to monitor prices and how they change, we can use a web scraper to extract just the information we want from a website and dump them into an excel file. In this tutorial, we will be learning how to scrape the web using beautifulsoup.
In other words, it’s a program that retrieves data from websites and parses it for specific data. BeautifulSoup is one of the most popular libraries used in web scraping. It’s used to parse HTML documents for data either through Python scripting or the use of CSS selectors.

The section element is used to group content by theme and represents a section of a document or application. Sections can have their own header and footer elements, and there can be multiple section elements used on a single page. The main element indicates to browsers and screen readers which portion of your markup contains the main section of content on a given page. This can help with keyboard command access, zooming on mobile browsers, and more.
Around all the elements in the return statement, this technically make the return statement to return only one value as a whole. S with roles are to overcome certain cross-platform styling limitations. Those classes are from a styling framework that helps with scoping CSS. What’s probably closer to the truth is that it doesn’t actually matter that much.
