强制 rvest 识别表格(html_tag(x) == "table" is not TRUE) [英] Coercing rvest to recognize tables (html_tag(x) == "table" is not TRUE)

问题描述

我似乎无法让 html_table() 工作.

I can't seem to ever get html_table() to work.

这是一个完美的例子:(试图刮 6 个游戏:表)

This is a perfect example: (Trying to scrape the 6 Games: table)

library(rvest)

hockey <- html("http://www.hockey-reference.com/boxscores/2015/3/6/")

hockey %>%
    html_nodes("#stats .tooltip , #stats td , #stats a") %>%
    html_table()

但我得到一个 html_tag(x) == "table" is not TRUE.很明显是一张桌子.

But I am getting a html_tag(x) == "table" is not TRUE. It's so obviously a table.

如何强制 rvest 将节点识别为表?

How can I coerce rvest to recognize the node as a table?

推荐答案

尝试:

hockey %>% html_table(fill = TRUE)

解析页面上的所有表格，或者

to parse all the tables on the page, or

hockey %>% html_nodes("#stats") %>% html_table()

只解析你想要的第一个.

to parse just the first one you're after.
