How to Make a Reusable Scraper With Beautiful Soup However, you can also scrape a webpage by calling a particular tag name with its corresponding id or class: data = soup.find_all( 'div', class_ = 'enter the target class name here') In essence, the line containing the id becomes: my_classes = soup.find(class_ = 'enter the target class name here') To bypass that error, you need to write an underscore in front of class like this: class_.
However, writing class directly results in syntax confusion as Python see it as a keyword. To do this for a class name, replace the id with class. Id = soup.find(id = 'enter the target id here') Let's look at an example of how you can scrape the content of a page below using the id: from bs4 import BeautifulSoup So, you don't need to use the for loop with it.

That block of code returns all h2 elements and their content. To load all the h2 elements, you can use the find_all built-in function and the for loop of Python: from bs4 import BeautifulSoup In the code snippet above, soup.h2 returns the first h2 element of the webpage and ignores the rest. To do this, you need to include the name of the target tag in your Beautiful Soup scraper request.įor example, let's see how you can get the content in the h2 tags of a webpage. You can also scrape the content in a particular tag with Beautiful Soup. How to Scrape the Content of a Webpage by the Tag Name text method: from bs4 import BeautifulSoup You can also get the pure content of a webpage without loading its element with the.
