R - Scrape a page and display a list of items

Question

Please help me scrape the page,

https://support.sas.com/en/papers/proceedings-archive/sugi2005.html

to display the list of Paper names. See below what I have so far, but I do not know the class to use to achieve this. Thanks for helping!

pagetoread <- read_html("http://www2.sas.com/proceedings/sugi30/toc.html",n=500)

get_paper_names <- function(html){
  html %>% 
    html_nodes('.?????') %>% 
    html_text() %>% 
    str_trim() %>% 
    unlist()
}

get_paper_names(pagetoread)

Answer 1

We can do,

'https://support.sas.com/en/papers/proceedings-archive/sugi2005.html' %>% read_html() %>% 
  html_nodes('#par > div > div:nth-child(3) > div > div.par.parsys > div > div') %>% html_nodes('p') %>% html_nodes('cite') %>% 
  html_text()
