Xpath not "seeing" table in Rvest-CodePudding

I am attempting to scrape table in this website. I have done it in several website but can't scrape in this website. Does it have anything to do with the fact that the table is generated and not static? Here is my code:

library(tidyverse) 
library(rvest)

link <- "https://portal.vietcombank.com.vn/Personal/TG/Pages/ty-gia.aspx?devicechannel=default" 
webpage <- read_html(link) 
webpage %>% 
    html_nodes(xpath = "//*[@class = 'tbl-01 rateTable']") %>% 
    html_table()

Thank all very much

CodePudding user response：

The data actually is present in another link which can be found out by looking under Networks tab in the browser.

library(rvest)

url <- 'https://portal.vietcombank.com.vn/UserControls/TVPortal.TyGia/pListTyGia.aspx?txttungay=5/10/2021&BacrhID=1&isEn=False'
data <- url %>% read_html %>% html_table() %>% .[[1]]
