将url表转换为`data.frame` R-XML-RCurl

Question

I'm trying to get the table of an url into a data.frame . In other examples I found the following code worked:

library(XML)
library(RCurl)
theurl <- "https://es.finance.yahoo.com/q/cp?s=BEL20.BR"
tables <- readHTMLTable(theurl)

As the warning says the table doesn't seem to be XML

Warning message: XML content does not seem to be XML: 'https://es.finance.yahoo.com/q/cp?s=BEL20.BR'

Alternatively, getURLContent(theurl, ssl.verifypeer = FALSE, useragent = "R") works but don't know how to extract the table. Any help would be appreciated.

EDIT: thanks to @har07 using table <- readHTMLTable(getURLContent(theurl, ssl.verifypeer = FALSE, useragent = "R"))$ yfncsumtab gives the output but still have to be filtered.

Answer 1

You can get the table if you use getURL to get the document content. Sometimes readHTMLTable has trouble getting content. In those cases, it is recommended to try getURL

> library(XML)
> library(RCurl)
> URL <- getURL("https://es.finance.yahoo.com/q/cp?s=BEL20.BR")
> rt <- readHTMLTable(URL, header = TRUE)
> rt

You might need to adjust the header argument and possibly others, but the tables are there.
