How can I scrape ads (e.g Banners) from a dynamically loaded web page - like AdblockPlus - using Python?
I want to exclude ads from a web page to filter it.
You can use BeautifulSoup to scrape webpage.
You need to install the package and just import it
Like this from bs4 import BeautifulSoup

I am new to this world of web scraping.
I was trying to scrape twitter with BeautifulSoup in Python.
Here's my code :
from bs4 import BeautifulSoup
import requests
request = requests.get("https://twitter.com/mybmc").text
soup = BeautifulSoup(request, 'html.parser')
print(soup.prettify())
But I am getting a large output which is not the twitter page which I am looking for but there is a error container :
Output Image
which says JavaScript is disabled in this browser. I tried changing my default browsers to Chrome, Firefox and Microsoft Edge but the out was same .
What should I do in this case?
Twitter here seem to be specifically trying to prevent scrapers of the front end, probably with the view that you should use their REST API to fetch that same data. It is not to do with your default browsers, but that requests.get will be providing a python requests user agent, which specifically doesn't support Javascript.
I'd suggest using a different page to practice on, or if it must be the twitter front page, consider using selenium perhaps with a standalone container to scrape.
I need to get the table on this website on live basis & unable download csv as the link is hidden in java script. Selenium is also not able access this website - https://www.nseindia.com/option-chain.
You can use beautifulsoup for scraping and get the table by id here is the doc
I am trying to scrape the table found https://ark.intel.com/content/www/us/en/ark/search/featurefilter.html?productType=873&1_Filter-Family=595&2_StatusCodeText=4
I tried using BeautifulSoup and Soup is unable to parse the info located inside the "body" tag. I get a null output when I try to parse the table.
How can I workaround this?
This page uses JavaScript to add data but BeautifulSoup/LXML can't run JavaScript - if you turn off javaScrip in browser and load page then you will see what BeautifulSoup/LXML can get.
You may need Selenium to control web browser which can run JavaScript.
Or you can try to use DevTools in Chrome/Firefox (tab Network) to get url usesJavaScript(AJAX/XHR) to download data. And you can try to use this url withrequestsandBeautifulSoup`
I found it uses url:
https://ark.intel.com/libs/apps/intel/support/ark/advancedFilterSearch?productType=873&1_Filter-Family=595&2_StatusCodeText=4&forwardPath=/content/www/us/en/ark/search/featurefilter.html&pageNo=1
I didn't check if requests will need special settings (ie. cookies, headers) to get it.
You can use Puppeteer to 'control' the dynamic web page, and scrape it with BS.
See here : https://github.com/puppeteer/puppeteer/tree/master/examples
I need to scrape a site with authentication and I'm planning on using my google account to do so.
So far I've done:
import requests
from bs4 import BeautifulSoup
url = "https://url.com/login"
r = requests.get(url)
When I tried to follow the Sign In with Google button, I realized that there's no href link within the HTML.
Anyone can help me with this?
Thanks!
BeautifulSoup is a library that does http request directly through python, meaning that there's no browser involved. That implies that you can't scrape websites that require things like login in.
Give a look to Selenium, a library that allows you to do request through your browser.
I'm using Selenium to scrape table data from a website. I found that I can easily iterate through the rows to get the information that I need using xcode. Does selenium keep hitting the website every time I search for an object's text by xcode? Or does it download the page first and then search through the objects offline?
If the former is true does is there a way to download the html and iterate offline using Selenium?
Selenium uses a Web Driver, similar to your web browser. Selenium will access/download the web page once, unless you've wrote the code to reload the page.
You can download the web page and access it locally in selenium. For example you could get selenium to access the web page "C:\users\public\Desktop\index.html"
