用Rvest解析网站

Question

library(rvest); library(XML); library(magrittr)
#> Loading required package: xml2
#> 
#> Attaching package: 'XML'
#> The following object is masked from 'package:rvest':
#> 
#>     xml

url <- 'http://www.screener.in/company/526965'

basic <- read_html(url)

basic %>% html_nodes('#balancesheet div')
#> {xml_nodeset (0)}

readHTMLTable(url)
#> named list()

如果您转到网址链接，则会有某些表格。我想在R中引入资产负债表。从代码中可以看出，readHTMLTable()和html_nodes()都返回空白而不是表格。
