And not just the content but also the structure. Hold your horses □! We know that coding is the fun part, but first, you'll need some understanding of the page you're trying to scrape. Now that we've got the basics, we can move on to the fun part. It is called nesting and is common in HTML, where almost all items are nested inside a parent tag. The example gets the first div, finds the header by ID, and an item with my-class inside that. soup.find("div").find(id="header").find(class_="my-class") As you can see, it might get complicated fast.Nodes can have multiple classes separated with spaces. soup.find(class_="my-class") returns the first item that contains the my-class class.IDs are unique, so there shouldn't be more items with the same one. soup.find(id="header") looks for a node which ID is header.soup.find("div") will get the first element that matches the div tag.For now, a quick guide on the fundamental selectors: We will build a functional web scraper with an example site in the following sections. It will be an object with the response's data: the HTML and other essential pieces such as status code. Then, use the get function to obtain the page and print the response. We will start by importing the library and defining a variable with the URL we want to access. Now that we've seen the basics, let's use Python and the Requests library to download a page. Depending on the browser and CSS file, it might have some default style like a blue color or underline. Go to is the text that the browser will show.href="" is the link's destination in case the user clicks the element.The CSS processor will interpret class="link-style", and it might show in a different color if so defined in the CSS file.Browsers also use this for internal navigation as anchors. id="example" gives the element a unique ID.Some of them are directly associated with a tag, like href with - URL of the link tag. CSS uses them for styling and Javascript for adding interactivity. They are optional but quite common, especially classes. HTML elements might have attributes such as class or id, which are name-value pairs, separated by =. Examples of that are and, which allow us to fill and send forms to the server, such as logging in and registering. Other components will control what can be done and not the display format. For example, will show text in bold, and will do so in italics. HTML "is the standard markup language for documents designed to be displayed in a web browser." It will structure the page using tags, each one meaning something different to the browser. But it is programmatically controlled, so you can extract the content you desire. In short, it launches a real browser to access the target webpage. If your case involves dynamic pages, you can go to our article on scraping with Selenium, a headless browser. That difference is usually called static vs. Some pages will load content later, but we will focus - for clarity - on those that load everything initially. However, the critical part for web scraping is the initial HTML. The browser is really doing a lot of work, but usually so fast that we don't even notice as users. Images are loaded and displayed where they should. Thanks to the behavior in the JS files, the infinite scroll works perfectly. Everything shows the style defined by the CSS file. The browser will handle all the requests/responses and render the final content. They can be used as part of the main content or as backgrounds. Javascript adds functionality and behavior, such as loading more job offers on infinite scroll.CSS will format and style the content (i.e., colors, fonts, and many more).In those extra resources are the ones mentioned above:
