Thank you for sharing this -- it was incredibly helpful for a project I was working on! I'm coding in Python, but your explanations were so clear that it was a snap to translate from R to python.
thank you for this, I have been trying to iterate through the list that exists right after the course name inside each rating. Any ideas on how to do that?
I can't seem to get started. I get the following error when I run the first line of code attempting to create the rs_driver_object. "Could not open chrome browser. Client error message: Undefined error in httr call. httr output: Failed to connect to localhost port 14415: Connection refused Check server log for further details. Warning message: In rsDriver(browser = "chrome", chromever = "111.0.5563.19", verbose = F, : Could not determine server status." Any idea how to fix this? I have java installed already so didn't need to download it. Also tried using chromever = NULL as seen on a stack post.
I'm trying to scrape through the subpagination of a page, but I think it's based on a Java mask. The pagination is not visible in the URL and there is no "Next" button in the pagination. Since I want to scrape with different search terms that produce search results of different lengths, the subpagination is always of different lengths. I am therefore looking for a method with which I can scrape paginations of different lengths for different search terms. Can you help me with this or do you have any advice for me? Thx!
Thank you for well-explained tutorial. Unfortunately, when practicing along, I encountered Error in if (file.access(phantompath, 1) < 0) { : argument is of length zero. Do you have a solution for it?
This is brilliant - perfect pace, content and 100% clear explanations. Awesome!
Amazing work Samer! I learned a lot from you within just 22 minutes! You solved a lot of my problems. Thank you so much!

Awesome to hear this, Dave!

Hi from Poland,
I have problem with the code.
My code: rs_driver_object
Me too :(
if u add
driver = chrome(port = 4567L, version = '109.0.5414.25')
before rsDriver, it would be work
@@quant_univ maybe clearing the environment & start over again, would work.
rm(list = ls())
gc()
Then run again your code chunk.
Please refer to my RSelenium Installation Guide tutorial on my channel. That should help :)
What if a website have multiple clickable elemets and i wish to click on all of them to expand them?

Hi Samer,
I love your videos of web scraping with R. Could you make a video to show how to web scrape AJAX webs?
Thanks!
Hi Olmedo!
Thank you for your feedback. This is a really good idea. I'll definitely explore it
