抓取维基（不是维基百科）信息框

Question

我可以使用 rvest 在任何维基百科网站上抓取信息框，但我想在维基页面上做同样的事情，但无法让它工作...

link：https://dc.fandom.com/wiki/Wonder_Woman_(Diana_Prince) 在页面上，您有信息框（看起来像普通的维基百科 table），CSS 选择器似乎是“.pi-layout-default”

我想要一个包含真实姓名、别名等的数据框。

知道怎么做吗？

使用 rvest 和 selectorgadet!

library(rvest)
library(tidyverse)

read_html("https://dc.fandom.com/wiki/Wonder_Woman_(Diana_Prince)") %>%
  html_nodes(".pi-font , .pi-data-label") %>%
  html_text() %>%
  matrix(ncol = 2, byrow = TRUE) %>%
  as_tibble()
# A tibble: 21 x 2
