Web crawler in R with heading and summary - r

Question

I'm trying to extract links from here with the article heading and a brief summary of each link.
The output should have the article heading and the brief summary of each article which is on the same page.
I'm able to get the links. Can you please suggest how can i get heading and summary for each link. Please see my code below.
install.packages('rvest')
#Loading the rvest package
library('rvest')
library(xml2)
#Specifying the url for desired website to be scrapped
url <- 'http://money.howstuffworks.com/business-profiles.htm'
webpage <- read_html(url)
pg <- read_html(url)
head(html_attr(html_nodes(pg, "a"), "href"))

Answer 1

We can use purrr to inspect each node and extract the relevant information:
library(rvest)
library(purrr)
url <- 'http://money.howstuffworks.com/business-profiles.htm'
articles <- read_html(url) %>%
html_nodes('.infinite-item > .media') %>%
map_df(~{
title <- .x %>%
html_node('.media-heading > h3') %>%
html_text()
head <- .x %>%
html_node('p') %>%
html_text()
link <- .x %>%
html_node('p > a') %>%
html_attr('href')
data.frame(title, head, link, stringsAsFactors = F)
})
head(articles)

Obligatory comment: In this case I saw no disclaimer against harvesting on their Terms and conditions, but always be sure to check the terms of a site before scraping it.
