In the next tutorial, we're going cover navigating a page's elements to get more specifically what you want. This concludes the introduction to Beautiful Soup. get_text() on a Beautiful Soup object, including the full soup: print(soup.get_text()) get('href') to get the true URL.įinally, you may just want to grab text. Therefore, examples using Python and Beautiful Soup will not work without some extra additions. However, the KanView website uses JavaScript links. text from the tag, you'd get the anchor text, but we actually want the link itself. Beautiful Soup is a popular Python library that makes web scraping by traversing the DOM (document object model) easier to implement. For example: for url in soup.find_all('a'): string on, we will get None returned.Īnother common task is to grab links. Notice that, if there are child tags in the paragraph item that we're attempting to use. The difference between string and text is that string produces a NavigableString object, and text is just typical unicode text. We can also iterate through them: for paragraph in soup.find_all('p'): What if we wanted to find them all? print(soup.find_all('p')) In the case above, we're just finding the first one. If you do print(soup) and print(source), it looks the same, but the source is just plain the response data, and the soup is an object that we can actually interact with, by tag, now, like so: # title of the pageįinding paragraph tags is a fairly common task. Then, we create the "soup." This is a beautiful soup object: soup = bs.BeautifulSoup(source,'lxml') To begin, we need to import Beautiful Soup and urllib, and grab source code: import bs4 as bs I have created an example page for us to work with. If not, do: $ pip install lxml or $ apt-get install python-lxml. You may already have it, but you should check (open IDLE and attempt to import lxml). Beautiful Soup also relies on a parser, the default is lxml. It works with your favorite parser to provide idiomatic ways of navigating. To use beautiful soup, you need to install it: $ pip install beautifulsoup4. Beautiful Soup is a Python library for pulling data out of HTML and XML files. Beautiful Soup is a Python library aimed at helping programmers who are trying to scrape data from websites. Welcome to a tutorial on web scraping with Beautiful Soup 4.
