我想用rvest在网站上刮一张表。我可以抓取页面上的几个元素，但不能抓取表或表内的元素。我怀疑这与表是一个"框架"有关。但到目前为止，我没有找到+抓取源html。
提前感谢!阿德里安·
# set up
library(rvest)
library(tidyverse)
# scraping
url <- "https://u.gg/lol/top-lane-tier-list?rank=iron"
main_page <- read_html(url)
patch <- html_node(main_page, "#stats-tables-container-ID > div.title-header > h1 > div") %>% html_text()
rank <- html_node(main_page, ".rank-option") %>% html_text()
table <- html_table(main_page, ".#stats-tables-container-ID > div.stats-tables__content-container > div > div > div > div.content-section.ReactTable.ugg-table-2.tier-list")
我能够提取表，但没有回报。我使用了以下代码:
library(stringr)
library(RSelenium)
url <- "https://u.gg/lol/top-lane-tier-list?rank=iron"
shell('docker run -d -p 4445:4444 selenium/standalone-firefox')
remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox")
remDr$open()
remDr$navigate(url)
web_Obj_Table <- remDr$findElement("xpath", '//*[@id="stats-tables-container-ID"]/div[6]/div/div/div/div[1]')
text_Table <- web_Obj_Table$getElementText()
text_Table <- stringr::str_split(text_Table, "n")
我得到了以下结果:
