How to extract links from a page using Beautiful soup

Question

I have a HTML Page with multiple divs like:

<div class="post-info-wrap">
  <h2 class="post-title"><a href="https://www.example.com/blog/111/this-is-1st-post/" title="Example of 1st post &#8211; Example 1 Post" rel="bookmark">sample post &#8211; example 1 post</a></h2>
  <div class="post-meta clearfix">

    <div class="post-info-wrap">
      <h2 class="post-title"><a href="https://www.example.com/blog/111/this-is-2nd-post/" title="Example of 2nd post &#8211; Example 2 Post" rel="bookmark">sample post &#8211; example 2 post</a></h2>
      <div class="post-meta clearfix">

and I need to get the value for all the divs with class post-info-wrap I am new to BeautifulSoup

so I need these urls:

• https://www.example.com/blog/111/this-is-1st-post/

• https://www.example.com/blog/111/this-is-2nd-post/

• and so on...

I have tried:

import re
import requests
from bs4 import BeautifulSoup

r = requests.get("https://www.example.com/blog/author/abc") 
data = r.content  # Content of response

soup = BeautifulSoup(data, "html.parser")
for link in soup.select('.post-info-wrap'):
   print link.find('a').attrs['href']

This code doesnt seem to be working. I am new to beautiful soup. How can i extract the links?

Answer 1

link = i.find('a',href=True) always not return anchor tag (a), it may be return NoneType, so you need to validate link is None, continue for loop,else get link href value.

Scrape link by url:

import re
import requests
from bs4 import BeautifulSoup
r = requests.get("https://www.example.com/blog/author/abc")
data = r.content  # Content of response
soup = BeautifulSoup(data, "html.parser")

for i in soup.find_all('div',{'class':'post-info-wrap'}):
   link = i.find('a',href=True)
   if link is None:
       continue
   print(link['href'])

Scrape link by HTML:

from bs4 import BeautifulSoup
html = '''<div class="post-info-wrap"><h2 class="post-title"><a href="https://www.example.com/blog/111/this-is-1st-post/" title="Example of 1st post &#8211; Example 1 Post" rel="bookmark">sample post &#8211; example 1 post</a></h2><div class="post-meta clearfix">
<div class="post-info-wrap"><h2 class="post-title"><a href="https://www.example.com/blog/111/this-is-2nd-post/" title="Example of 2nd post &#8211; Example 2 Post" rel="bookmark">sample post &#8211; example 2 post</a></h2><div class="post-meta clearfix">'''

soup = BeautifulSoup(html, "html.parser")

for i in soup.find_all('div',{'class':'post-info-wrap'}):
   link = i.find('a',href=True)
   if link is None:
       continue
   print(link['href'])

Update:

from bs4 import BeautifulSoup
from selenium import webdriver

driver = webdriver.Chrome('/usr/bin/chromedriver')
driver.get("https://www.example.com/blog/author/abc")

soup = BeautifulSoup(driver.page_source, "html.parser")

for i in soup.find_all('div', {'class': 'post-info-wrap'}):
    link = i.find('a', href=True)
    if link is None:
        continue
    print(link['href'])

Answer 2

You can use soup.find_all:

from bs4 import BeautifulSoup as soup
r = [i.a['href'] for i in soup(html, 'html.parser').find_all('div', {'class':'post-info-wrap'})]

Output:

['https://www.example.com/blog/111/this-is-1st-post/', 'https://www.example.com/blog/111/this-is-2nd-post/']
