QUESTION
I am hoping someone can please help me out and put me out of my misery. I have recently started to learn Python and wanted to challenge myself with some web-scraping.
Over the past couple of days I have been trying to web-scrape this website (https://ebn.eu/?p=members). On the website, I am interesting in:
- Clicking on each logo image which brings up a pop-up
- From the pop-up scrape the link which is behind the text "VIEW FULL PROFILE"
- Move to the next logo and do the same for each
I have managed to get Selenium up and running but the issue is that it keeps opening the first logo and copying the same link as opposed to moving to the next one. I have tried in various different ways but came up against a brick wall.
My code so far:
...ANSWER
Answered 2021-Apr-02 at 05:00If you study the HTML of the page, they have the onclick script which basically triggers the JS and renders the pop-up. You can make use of it.
You can find the onclick script in the child element img
.
So your logic should be like (1)Get the child element (2)go to first child element (which is img always for your case) (3)Get the onclick script text (4)execute the script.
QUESTION
According to the reply I found in my previous question, I am able to grab the table by web scraping in Python from the URL: https://www.nytimes.com/interactive/2021/world/covid-vaccinations-tracker.html
But it only grabs partially until the row "Show all" is appeared.
How can I grab the complete table in Python which is hidden beyond "Show all" ?
Here is the code I am using:

QUESTION
I am trying to read the content of the following webpage (as shown in the Inspect Element tool of my browser) into R:
Since the content is apparently Javascript-rendered, it is not possible to retrieve content by using common web scraping functions like read_html
from xml2
package. I have come across the following post that suggests using rvest
and V8
packages, but I could not get it to work for my problem:
https://datascienceplus.com/scraping-javascript-rendered-web-content-using-r/
I have also seen very similar questions on Stack Overflow (like this and this), but the answers to those questions (the hidden api solution and the Request URL in the Network tab) did not work for me.
For starters, I am interested in reading the public ID of people in the list (the div.user-nickname
node). My guess is that either I am specifying the node incorrectly or the website does not allow web scraping at all.
Any help would be greatly appreciated.

Answered 2021-Apr-18 at 18:19Data is coming from an API call returning json. You can make the same GET request and then extract the usernames. Swop x$UserName
with x$CustomerId
for ids.
QUESTION
I am scraping a grocery website (https://www.paknsaveonline.co.nz) to do some meal planning before I shop. The price of products varies with the location of the store. I want to extract prices from my local store (Albany).
I am new to web-scraping, but I am assuming my code must
- change the default store to my local store (Albany, using this url: https://www.paknsaveonline.co.nz/CommonApi/Store/ChangeStore?storeId=65defcf2-bc15-490e-a84f-1f13b769cd22)
- maintain a single requests "session", to ensure I scrape all of my products from the same store site.
My scraping code successfully scrapes the price of broccoli, but the price does not align with the price from my local store. At the time of posting my scraped price for broccoli is $1.99, but when I manually check the price at the Albany store, the price is $0.99. I assume my code to switch to the correct store isn't working as intended.
Can anyone point out what I am doing wrong and suggest a solution?
Environment details:
- requests==2.23.0
- beautifulsoup4==4.6.3
- Python 3.7.10
Code below, with an associated link to Google Colab file.
...ANSWER
Answered 2021-Apr-10 at 08:08When I saw the actual requests of that you need to first get some cookies from base URL and then you can change the store for that session you cant directly modify the store by calling that URL so first you call base URL and then change store URL and then again call the base URL to get 0.99
cents price.
