BeautifulSoup - Scraping Link from HTML
While scraping and analysing the content from resources with a website, you are often required to extract all the links that a certain page contains. In this chapter, we shall find out how we can extract links from a HTML document.
HTML has the anchor tag <a> to insert a hyperlink. The href attribute of anchor tag lets you to establish the link. It uses the following syntax −
<a href=="web page URL">hypertext</a>
With the find_all() method we can collect all the anchor tags in a document and then print the value of href attribute of each of them.
In the example below, we extract all the links found on Google's home page. We use requests library to collect the HTML contents of https://google.com, parse it in a soup object, and then collect all <a> tags. Finally, we print href attributes.
Example
from bs4 import BeautifulSoup import requests url = "https://www.google.com/" req = requests.get(url) soup = BeautifulSoup(req.content, "html.parser") tags = soup.find_all('a') links = [tag['href'] for tag in tags] for link in links: print (link)
Here's the partial output when the above program is run −
Output
https://www.google.co.in/imghp?hl=en&tab=wi https://maps.google.co.in/maps?hl=en&tab=wl https://play.google.com/?hl=en&tab=w8 https://www.youtube.com/?tab=w1 https://news.google.com/?tab=wn https://mail.google.com/mail/?tab=wm https://drive.google.com/?tab=wo https://www.google.co.in/intl/en/about/products?tab=wh http://www.google.co.in/history/optout?hl=en /preferences?hl=en https://accounts.google.com/ServiceLogin?hl=en&passive=true&continue=https://www.google.com/&ec=GAZAAQ /advanced_search?hl=en-IN&authuser=0 https://www.google.com/url?q=https://io.google/2023/%3Futm_source%3Dgoogle-hpp%26utm_medium%3Dembedded_marketing%26utm_campaign%3Dhpp_watch_live%26utm_content%3D&source=hpp&id=19035434&ct=3&usg=AOvVaw0qzqTkP5AEv87NM-MUDd_u&sa=X&ved=0ahUKEwiPzpjku-z-AhU1qJUCHVmqDJoQ8IcBCAU
However, a HTML document may have hyperlinks of different protocol schemes, such as mailto: protocol for link to an email ID, tel: scheme for link to a telephone number, or a link to a local file with file:// URL scheme. In such a case, if we are interested in extracting links with https:// scheme, we can do so by the following example. We have a HTML document that consists of hyperlinks of different types, out of which only ones with https:// prefix are being extracted.
html = ''' <p><a href="https://www.tutorialspoint.com">Web page link </a></p> <p><a href="https://www.example.com">Web page link </a></p> <p><a href="mailto:nowhere@mozilla.org">Email link</a></p> <p><a href="tel:+4733378901">Telephone link</a></p> ''' from bs4 import BeautifulSoup import requests soup = BeautifulSoup(html, "html.parser") tags = soup.find_all('a') links = [tag['href'] for tag in tags] for link in links: if link.startswith("https"): print (link)
