This concludes the introduction to Beautiful Soup.
#Web scraping with beautiful soup full#
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. text from the tag, you'd get the anchor text, but we actually want the link itself. 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 use a regular expression, Beautiful Soup, and CSS selectors. We can also iterate through them: for paragraph in soup.find_all('p'): There are three standard methods we can use to scrape data from a web page on a website. 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.
#Web scraping with beautiful soup install#
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.
