rvest limits the results to 24 items - r

Question

Good evening everyone,
I am currently trying to scrape zalando website to get the name of every products that appaears on the first two pages of the following url : (https://www.zalando.nl/damesschoenen-sneakers/)
Here is my code:
require(rvest)
require(dplyr)
url <- read_html('https://www.zalando.nl/damesschoenen-sneakers/')
selector_name <- '.z-nvg-cognac_brandName-2XZRz'
output <- html_nodes(x = url, css = selector_name) %>% html_text
The result is a list of 24 items while there is 86 products on the page. Has anyone encounter this issue before ? Any idea on how to solve it ?
Thank you for your help.
Thomas

Answer 1

I just tried what Nicolas Velasqueaz suggested
url <- read_html('https://www.zalando.nl/damesschoenen-sneakers/')
write_html(url, file = "test_url.html")
selector_name <- '.z-nvg-cognac_brandName-2XZRz'
test_file <- read_html("test_url.html")
output <- html_nodes(x = test_file, css = selector_name) %>% html_text
The results are the same. I still have only 24 items that shows up.
So if anyone has a solution would be very appreciated.

Answer 2

Thank you for your kind answer. I will dive into that direction.
I also find a way to get the name of the brand without RSelenium, here si my code:
library('httr')
library('magrittr')
library('rvest')
################# FUNCTION #################
extract_data <- function(firstPosition,lastPosition){
mapply(function(first,last){
substr(pageContent, first, last) %>%
gsub( "\\W", "\\1 ",.) %>%
gsub("^ *|(?<= ) | *$", "", ., perl = TRUE)
},
firstPosition, lastPosition )
}
############################################
url <- 'https://www.zalando.nl/damesschoenen-sneakers/'
page <- GET(url)
pageContent <- content(page, as='text')
# Get the brand name of the products
firstPosition <-
unlist(gregexpr('brand_name',pageContent))+nchar('brand_name')+1
lastPosition <- unlist(gregexpr('is_premium',pageContent))-2
extract_data(firstPosition, lastPosition)
Unfortunately it starts being difficult when you want something else than brand name so maybe that the best soution is to do it with RSelenium.
