Why is Python Beautiful Soup stripping parameters from the scraped URL - python

I'm trying to scrape this website with Python BeautifulSoup. And my code below is first fetching all the links from the page. While fetching the links it is stripping ampersands and parameters from the original link. I wonder why? Would somebody know? I've got the code down here along with the output.
from bs4 import BeautifulSoup as bs
import requests
url = requests.get ("http://mnregaweb4.nic.in/netnrega/demand_emp_demand.aspx?lflag=eng&file1=dmd&fin=2017-2018&fin_year=2017-2018&source=national&Digest=x44uSVqhiyzomN66Te0ELQ")
soup = bs(url.text, 'xml')
state= soup.find(id = "t1")
state_links = []
for link in soup.find_all('a', href= True):
state_links.append(link['href'])
state_links = [e for e in state_links if e not in ("javascript:history.go(-1);", "http://164.100.129.6/netnrega/MISreport4.aspx?fin_year=2013-2014rpt=RP&source=national", "javascript:__doPostBack('ctl00$ContentPlaceHolder1$LinkButton1','')")]
for dis_link in state_links:
# print (dis_link)
link_new = "http://mnregaweb4.nic.in/netnrega/"+dis_link
print (link_new)
Output:
Actual Link: http://mnregaweb4.nic.in/netnrega/demand_emp_demand.aspx?file1=dmd&page1=s&lflag=eng&state_name=ANDHRA+PRADESH&state_code=02&fin_year=2017-2018&source=national&Digest=4jL5hchs+iT7xqB6T/UXzw
(Highlighted stuff in code is missing from the scraped link)
Scraped link: http://mnregaweb4.nic.in/netnrega/demand_emp_demand.aspx?file1=dmd=s=eng=ANDHRA+PRADESH=02=2017-2018=national=4jL5hchs+iT7xqB6T/UXzw

It might be because you are trying to parse it with 'xml', instead try to parse it with 'html.parser',
I am getting the following result with the code below:
from bs4 import BeautifulSoup as bs
import requests
url = requests.get ("http://mnregaweb4.nic.in/ne....")
soup = bs(url.text, 'html.parser')
state_links = []
for link in soup.find_all('a', href=True):
state_links.append(link['href'])
print(state_links)
# 'demand_emp_demand.aspx?file1=dmd&page1=s&lflag=eng&state_name=ANDHRA+PRADESH&state_code=02&fin_year=2017-2018&source=national&Digest=4jL5hchs+iT7xqB6T/UXzw'

This issue is about the parser used in Beautifulsoup.
Try with
soup = bs(url.text, 'html.parser')
or
soup = bs(url.text, 'lxml')
You might need to install some specific parser, see this chapter of the doc.

Web scraping IMDB with Python's Beautiful Soup

I am trying to parse this page "https://www.imdb.com/title/tt0068112/?ref_=fn_al_tt_1", but I can't find the href that I need (href="/title/tt0068112/episodes?ref_=tt_eps_sm").
I tried with this code:
url="https://www.imdb.com/title/tt0068112/?ref_=fn_al_tt_1"
page(requests.get(url)
soup=BeautifulSoup(page.content,"html.parser")
for a in soup.find_all('a'):
print(a['href'])
What's wrong with this? I also tried to check "manually" with print(soup.prettify()) but it seems that that link is hidden or something like that.
You can get the page html with requests, the href item is in there, no need for special apis. I tried this and it worked:
import requests
from bs4 import BeautifulSoup
page = requests.get("https://www.imdb.com/title/tt0068112/?ref_=fn_al_tt_1")
soup = BeautifulSoup(page.content, "html.parser")
scooby_link = ""
for item in soup.findAll("a", href="/title/tt0068112/episodes?ref_=tt_eps_sm"):
print(item["href"])
scooby_link = "https://www.imdb.com" + "/title/tt0068112/episodes?ref_=tt_eps_sm"
print(scooby_link)
I'm assuming you also wanted to save the link to a variable for further scraping so I did that as well. 🙂
To get the link with Episodes you can use next example:
import requests
from bs4 import BeautifulSoup
url = "https://www.imdb.com/title/tt0068112/?ref_=fn_al_tt_1"
soup = BeautifulSoup(requests.get(url).content, "html.parser")
print(soup.select_one("a:-soup-contains(Episodes)")["href"])
Prints:
/title/tt0068112/episodes?ref_=tt_eps_sm

How to select all links of apps from app store and extract its href?

from bs4 import BeautifulSoup
import requests
from urllib.request import urlopen
url = f'https://www.apple.com/kr/search/youtube?src=globalnav'
response = requests.get(url)
html = response.text
soup = BeautifulSoup(html, 'html.parser')
links = soup.select(".rf-serp-productname-list")
print(links)
I want to crawl through all links of shown apps. When I searched for a keyword, I thought links = soup.select(".rf-serp-productname-list") would work, but links list is empty.
What should I do?
Just check this code, I think is what you want:
import re
import requests
from bs4 import BeautifulSoup
pages = set()
def get_links(page_url):
global pages
pattern = re.compile("^(/)")
html = requests.get(f"your_URL{page_url}").text # fstrings require Python 3.6+
soup = BeautifulSoup(html, "html.parser")
for link in soup.find_all("a", href=pattern):
if "href" in link.attrs:
if link.attrs["href"] not in pages:
new_page = link.attrs["href"]
print(new_page)
pages.add(new_page)
get_links(new_page)
get_links("")
Source:
https://gist.github.com/AO8/f721b6736c8a4805e99e377e72d3edbf
You can change the part:
for link in soup.find_all("a", href=pattern):
#do something
To check for a keyword I think
You are cooking a soup so first at all taste it and check if everything you expect contains in it.
ResultSet of your selection is empty cause structure in response differs a bit from your expected one from the developer tools.
To get the list of links select more specific:
links = [a.get('href') for a in soup.select('a.icon')]
Output:
['https://apps.apple.com/kr/app/youtube/id544007664', 'https://apps.apple.com/kr/app/%EC%BF%A0%ED%8C%A1%ED%94%8C%EB%A0%88%EC%9D%B4/id1536885649', 'https://apps.apple.com/kr/app/youtube-music/id1017492454', 'https://apps.apple.com/kr/app/instagram/id389801252', 'https://apps.apple.com/kr/app/youtube-kids/id936971630', 'https://apps.apple.com/kr/app/youtube-studio/id888530356', 'https://apps.apple.com/kr/app/google-chrome/id535886823', 'https://apps.apple.com/kr/app/tiktok-%ED%8B%B1%ED%86%A1/id1235601864', 'https://apps.apple.com/kr/app/google/id284815942']

How to extract url/links that are contents of a webpage with BeautifulSoup

So the website I am using is : https://keithgalli.github.io/web-scraping/webpage.html and I want to extract all the social media links on the webpage.
import requests
from bs4 import BeautifulSoup as bs
r = requests.get('https://keithgalli.github.io/web-scraping/webpage.html')
soup = bs(r.content)
links = soup.find_all('a', {'class':'socials'})
actual_links = [link['href'] for link in links]
I get an error, specifically:
KeyError: 'href'
For a different example and webpage, I was able to use the same code to extract the webpage link but for some reason this time it is not working and I don't know why.
I also tried to see what the problem was specifically and it appears that
links is a nested array where links[0] outputs the entire content of the ul tag that has class=socials so its not iterable so to speak since the first element contains all the links rather than having each social li tag be seperate elements inside links
Here is the solution using css selectors:
import requests
from bs4 import BeautifulSoup as bs
r = requests.get('https://keithgalli.github.io/web-scraping/webpage.html')
soup = bs(r.content, 'lxml')
links = soup.select('ul.socials li a')
actual_links = [link['href'] for link in links]
print(actual_links)
Output:
['https://www.instagram.com/keithgalli/', 'https://twitter.com/keithgalli', 'https://www.linkedin.com/in/keithgalli/', 'https://www.tiktok.com/#keithgalli']
Why not try something like:
import requests
from bs4 import BeautifulSoup as bs
r = requests.get('https://keithgalli.github.io/web-
scraping/webpage.html')
soup = bs(r.content)
links = soup.find_all('a', {'class':'socials'})
actual_links = [link['href'] for link in links if 'href' in link.keys()]
After gaining some new information from you and visiting the webpage, I've realized that you did the following mistake:
The socials class is never used in any a-element and thus you won't find any such in your script. Instead you should look for the li-elements with the class "social".
Thus your code should look like:
import requests
from bs4 import BeautifulSoup as bs
r = requests.get('https://keithgalli.github.io/web-
scraping/webpage.html')
soup = bs(r.content, "lxml")
link_list_items = soup.find_all('li', {'class':'social'})
links = [item.find('a').get('href') for item in link_list_items]
print(links)

Beautiful Soup can't find most of the tags

I am trying to scrape this page https://ntrs.nasa.gov/search .
I am using the code below and Beautiful soup is finding only 3 tags when there are many more. I have tried using html5lib, lxml and HTML parsers but none of them have worked.
Can you advise what might be the problem please?
import requests
import urllib.request
import time
from bs4 import BeautifulSoup
# Set the URL
url = 'https://ntrs.nasa.gov/search'
# Connect to the URL
response = requests.get(url)
# Parse HTML and save to a BeautifulSoup object¶
soup = BeautifulSoup(response.content, "html5lib")
# soup = BeautifulSoup(response.text, "html5lib")
# soup = BeautifulSoup(response.content, "html.parser")
# soup = BeautifulSoup(response.content, "lxml")
# loop through all a-tags
for a_tag in soup.findAll('a'):
if 'title' in a_tag:
if a_tag['title'] == 'Download Document':
link = a_tag['href']
download_url = 'https://ntrs.nasa.gov' + link
urllib.request.urlretrieve(download_url,'./'+link[link.find('/citations/')+1:11])
It is dynamically pulled from a script tag. You can regex out the JavaScript object which contains the download url, handle some string replacements for html entities, parse as json then extract the desired url:
import requests, re, json
r = requests.get('https://ntrs.nasa.gov/search')
data = json.loads(re.search(r'(\{.*/api.*\})', r.text).group(1).replace('&q;','"'))
print('https://ntrs.nasa.gov' + data['http://ntrs-proxy-auto-deploy:3001/citations/search']['results'][0]['downloads'][0]['links']['pdf'])
You could append the ?attachment=true but I don't think that is required.
Your problem stems from the fact that the page is rendered using Javascipt, and the actual page source is only a few script and style tags.

Extracting links from html from the link of the following website

I want to extract the link
/stocks/company_info/stock_news.php?sc_id=CHC&scat=&pageno=2&next=0&durationType=Y&Year=2018&duration=1&news_type=
from the html of the page
http://www.moneycontrol.com/company-article/piramalenterprises/news/PH05#PH05
The following is the code that is used
url_list = "http://www.moneycontrol.com/company-article/piramalenterprises/news/PH05#PH05"
html = requests.get(url_list)
soup = BeautifulSoup(html.text,'html.parser')
link = soup.find_all('a')
print(link)
using beautiful soup. How would I go about it, using find_all('a") doesn't return the required link in the returned html.
Please try this to get Exact Url you want.
import bs4 as bs
import requests
import re
sauce = requests.get('https://www.moneycontrol.com/stocks/company_info/stock_news.php?sc_id=CHC&durationType=Y&Year=2018')
soup = bs.BeautifulSoup(sauce.text, 'html.parser')
for a in soup.find_all('a', href=re.compile("company_info")):
# print(a['href'])
if 'pageno' in a['href']:
print(a['href'])
output:
/stocks/company_info/stock_news.php?sc_id=CHC&scat=&pageno=2&next=0&durationType=Y&Year=2018&duration=1&news_type=
/stocks/company_info/stock_news.php?sc_id=CHC&scat=&pageno=3&next=0&durationType=Y&Year=2018&duration=1&news_type=
You just have to use the get method to find the href attribute:
from bs4 import BeautifulSoup as soup
import requests
url_list = "http://www.moneycontrol.com/company-article/piramalenterprises/news/PH05#PH05"
html = requests.get(url_list)
page= soup(html.text,'html.parser')
link = page.find_all('a')
for l in link:
print(l.get('href'))
