Using rvest to scrape data that is not in table

问题

I'm trying to scrape some data from a website. I thought I could use rvest, but I'm having a lot of trouble getting data that is not in a table.

I don't know if it's possible, or whether I'm using the wrong package?

I am trying to get the website, name and address from the following html:

<div class="info clearfix">
<i class="sprite icon title"></i>
<p class="title">
<a target="_blank" href="https://test.com/regions/Tennis_Court.html">
Tennis Court</a>
</p>
<p class="location"> 123 Page St, Charlestown</p>                                                <p class="excerpt" itemprop="description">A place to play tennis</p>                                                                                           </div>

I'd hoped I could use something like html_node("title") etc, but that doesn't seem to wrong. Am I completely on the wrong path?

You can use html_nodes to add css selectors to extract :

library(rvest)
url <- 'https://concreteplayground.com/auckland/bars'

webpage <- url %>% read_html()
name <- webpage %>% html_nodes('p.name a') %>%html_text() %>% trimws()
address <- webpage %>% html_nodes('p.address') %>% html_text() %>% trimws()
links <- webpage %>% html_nodes('p.name a') %>% html_attr('href')
data.frame(name, address, links)

#                              name                                address
#1                         Holy Hop          498 New North Road, Kingsland
#2                              Sly          354A Karangahape Road, Newton

#                                                                 links
#1                         https://concreteplayground.com/auckland/bars/holy-hop
#2                              https://concreteplayground.com/auckland/bars/sly
