Web Scrapping Tutorial 3: Scrolling Down and Expanding Reviews by Presssing More
2024-05-23
Introduction
In this tutorial, we will look at how we can use Rselenium to :
- Scroll Down the review page
- Expand reviews by pressing More
We will also extract the text review along with time stamp and rating given
Step 0: Installing Libraries
package.name<-c("tidyverse","RSelenium")
for(i in package.name){
if(!require(i,character.only = T)){
install.packages(i)
}
library(i,character.only = T)
}Loading required package: tidyverse── Attaching core tidyverse packages ──────────────────────── tidyverse 2.0.0 ──
✔ dplyr 1.1.4 ✔ readr 2.1.5
✔ forcats 1.0.0 ✔ stringr 1.5.1
✔ ggplot2 3.5.0 ✔ tibble 3.2.1
✔ lubridate 1.9.3 ✔ tidyr 1.3.1
✔ purrr 1.0.2
── Conflicts ────────────────────────────────────────── tidyverse_conflicts() ──
✖ dplyr::filter() masks stats::filter()
✖ dplyr::lag() masks stats::lag()
ℹ Use the conflicted package (<http://conflicted.r-lib.org/>) to force all conflicts to become errors
Loading required package: RSeleniumStep 1:Start a headless Firefox browser
The syntax for initiating a headless Firefox browser is shown below
driver <- rsDriver(
browser = c("firefox"),
chromever = NULL,
verbose = F,
extraCapabilities = list("firefoxOptions" = list(args = list("--headless")))
)
web_driver <- driver[["client"]]
Once I execute this, Firefox browser would pop up in the
background as shown below.
Step 2: Navigate to the web page
Once you see the above page, we now have to go to the “patanjali store in powai” page in google maps. To do this, we will use the following lines of code
nm<-"patanjali store in powai "
ad_url<-str_c("https://www.google.co.id/maps/search/ ",nm)
# Now navigate to the URL.This is for the browser to go to that location
web_driver$navigate(ad_url)Once I execute the above, Firefox browser would go to the Jumbo Vada Pav page.
Step 3: Getting the URL for each store
We can see that there are 4 stores here.We will get the information for lets say one of the stores to understand the process in more detail.Once we are familiar with the process, we can replicate it for the other stores as well.
For this, we will have to follow a two steps process:
- Get the URL for each store
- Once you get the URL, access the URL link and then get the name and address
Get the XML path of the URL link through Inspection. The XML path for the three stores would look like the below:
- /html/body/div[2]/div[3]/div[8]/div[9]/div/div/div[1]/div[2]/div/div[1]/div/div/div[1]/div[1]/div[3]/div/a
- /html/body/div[2]/div[3]/div[8]/div[9]/div/div/div[1]/div[2]/div/div[1]/div/div/div[1]/div[1]/div[5]/div/a
- /html/body/div[2]/div[3]/div[8]/div[9]/div/div/div[1]/div[2]/div/div[1]/div/div/div[1]/div[1]/div[7]/div/a
The difference between the three is only wrt to the penultimate div element. For the first store it is div[3],for the second store it is div[5] and for the third it is div[7]
Now we will use this information to extract all the links. For each of these XML path, we need to get the href(url)
The penultimate div which is the only difference between the store XML paths will be specified as div(instead of div[3],div[5] or div[7]) and then each of these elements, we will extract the href using
# l1<-list()
link_Store <- web_driver$findElements(using = "xpath", value = "/html/body/div[2]/div[3]/div[8]/div[9]/div/div/div[1]/div[2]/div/div[1]/div/div/div[1]/div[1]/div/div/a")
# print(store)
l1<-list()
for(i in 1:length(link_Store) ){
l1[[i]]<-link_Store[[i]]$getElementAttribute("href")[[1]]
}
l1[[1]]
[1] "https://www.google.co.id/maps/place/Anmol+Patanjali+Store/data=!4m7!3m6!1s0x3be7c9e659d3c0e7:0xcd3cb45a143317ea!8m2!3d19.1202659!4d72.8897626!16s%2Fg%2F11p5jw_gg8!19sChIJ58DTWebJ5zsR6hczFFq0PM0?authuser=0&hl=en&rclk=1"

Step 4: Navigating to the Second Store
Lets take the second store for our illustration.It has an average rating of 3.3 and has 21 reviews.Lets navigate to this store first
web_driver$navigate(l1[[2]])Once we are on Store 2, we have to do the following things:
- Press the Review Page so that reviews are visible
- Scroll down all the way to the bottom so that are the reviews are visible
- There are some reviews for which More button is present. We need to press it
- Extract the element which has the info for each review
- Extract relevant info such as text, rating and time stamp
Step 4a: Pressing the Review Page
Review_botton_xpath_store2<-"/html/body/div[2]/div[3]/div[8]/div[9]/div/div/div[1]/div[2]/div/div[1]/div/div/div[3]/div/div/button[2]/div[2]/div[2]"
Review_botton_element_store2<-web_driver$findElement(using = "xpath",
value = Review_botton_xpath_store2)
Review_botton_element_store2$clickElement()Once we execute the above, we will be inside the review page as shown below
Step 4b: Scrolling Down the Page
In this step, we need to get the xpath for the scrollable bar.
This is a little tricky as might be difficult to identify the element through inspection as you will find that there are multiple elements that might look like scroll bar.But we have to proceed as shown in the screenshot below
You just have to search for scroll in the search bar. You will get some options. Get to the elements which has event and scroll in it. Hack - I have found that for most google reviews, scroll down is the same element.So you can use the xpath that we get for the above and use it in any scenario.
We also see that we might have to scroll down multiple times to view the entire review page.In one scroll, around 5 reviews are present.Hence in order to cover all the reviews, we will have to scroll down 4 times
# Scroll to the end
scrollable_div <-
try(web_driver$findElements(using = "xpath",
value = "/html/body/div[2]/div[3]/div[8]/div[9]/div/div/div[1]/div[2]/div/div[1]/div/div/div[2]"))
num_revies<-21
for (i in 1:ceiling(num_revies / 10 ) + 1) {
try(web_driver$executeScript("arguments[0].scrollTop = arguments[0].scrollHeight",
scrollable_div))
Sys.sleep(0.5)
print("Yes")
}[1] "Yes"
[1] "Yes"
[1] "Yes"For now, lets assume that we would have to run the executescript function with the given arguments to reach the bottom of the page.I got it from a google search.
After executing this, we will be at the bottom of the page as shown below
Step 4c: Pressing the More Button
There are few reviews for which More has to be clicked in order to expand the views.The first two reviews on this page has More option.So we need to get the xpath for these.
If we right click on More and inspect the element, we get the following
So, the logic to click these More buttons will be the following:
- Get the Element using xpath
- Click on the element
- Do the above while we are able to get More such elements
tryCatch({
Sys.sleep(1)
suppressMessages({
# Get the element using xpath
loadmore <- web_driver$findElement("xpath", "//*[@class='w8nwRe kyuRq']")
# While we are able to get the element, continue clicking on it
while(loadmore$isElementDisplayed()[[1]]){
loadmore$clickElement()
# Adding time buffers
Sys.sleep(0.5)
# Find the element again
loadmore <- web_driver$findElement("xpath", "//*[@class='w8nwRe kyuRq']")
loadmore$getElementText()[[1]]
}
})
},
error = function(e) {
NA_character_
}
)[1] NAAfter running the above, we can see that the More option is not there anymore as shown through the below screenshot
Step 4d: Getting Text, time stamp and rating for a review
For this, we have to get the element which has all the info on text, rating and time stamp. We need to check some elements through inspect but this is how it should look like
complete_text <- web_driver$findElements(using = "xpath",
value = "//*[@class='GHT2ce']")
length(complete_text)[1] 21As you can see that we have got the info for all the 21 reviews as the length of complete text is 21
ls_text<-list()
for (i in 1:length(complete_text)) {
ls_text[[i]]<-complete_text[[i]]$getElementText()[[1]]
Sys.sleep(0.5)
}
ls_text[1:3][[1]]

For this, we need to inspect the element as shown below. As ratings are given for each review, hence we can assume that the xml path will yield 21 stars as a result
complete_star <- web_driver$findElements(using = "xpath",
value = "//*[@class='kvMYJc']")
length(complete_star)[1] 21As you can see that we have got the info for all the 21 reviews as the length of complete star is 21
Getting the star rating for each review
ls_star<-list()

ls_star[[i]]<-complete_star[[i]]$getElementAttribute("aria-label")[[1]]
