How to retrieve text below titles from google search using rvest - r

Question

This is a follow up question for this one:
How to retrieve titles from google search using rvest
In this time I am trying to get the text behind titles in google search (circled in red):
Due to my lack of knowledge in web design I do not know how to formulate the xpath to extract the text below titles.
The answer by #AllanCameron is very useful but I do not know how to modify it:
library(rvest)
library(tidyverse)
#Code
#url
url <- 'https://www.google.com/search?q=Mario+Torres+Mexico'
#Get data
first_page <- read_html(url)
titles <- html_nodes(first_page, xpath = "//div/div/div/a/h3") %>%
html_text()
Many thanks for your help!

This can all be done without Selenium, using rvest. Unfortunately, Google works differently in different locales, so for example in my locale there is a consent page that has to be navigated before I can even send a request to Google.
It seems this is not required in the OPs locale, but for those if you in the UK, you might need to run the following code first for the rest to work:
library(rvest)
library(tidyverse)
url <- 'https://www.google.com/search?q=Mario+Torres+Mexico'
google_handle <- httr::handle('https://www.google.com')
httr::GET('https://www.google.com', handle = google_handle)
httr::POST(paste0('https://consent.google.com/save?continue=',
'https://www.google.com/',
'&gl=GB&m=0&pc=shp&x=5&src=2',
'&hl=en&bl=gws_20220801-0_RC1&uxe=eomtse&',
'set_eom=false&set_aps=true&set_sc=true'),
handle = google_handle)
url <- httr::GET(url, handle = google_handle)
For the OP and those without a Google consent page, the set up is simply:
library(rvest)
library(tidyverse)
url <- 'https://www.google.com/search?q=Mario+Torres+Mexico'
Next we define the xpaths we are going to use to extract the title (as in the previous Q&A), and the text below the title (pertinent to this question)
title <- "//div/div/div/a/h3"
text <- paste0(title, "/parent::a/parent::div/following-sibling::div")
Now we can just apply these xpaths to get the correct nodes and extract the text from them:
first_page <- read_html(url)
tibble(title = first_page %>% html_nodes(xpath = title) %>% html_text(),
text = first_page %>% html_nodes(xpath = text) %>% html_text())
#> # A tibble: 9 x 2
#> title text
#> <chr> <chr>

The subtext you refer to appears to be rendered in JavaScript, which makes it difficult to access with conventional read_html() methods.
Here is a script using RSelenium which gets the results necessary. You can also click the next page element if you want to get more results etc.
library(wdman)
library(RSelenium)
library(tidyverse)
selServ <- selenium(
port = 4446L,
version = 'latest',
chromever = '103.0.5060.134', # set to available
)
remDr <- remoteDriver(
remoteServerAddr = 'localhost',
port = 4446L,
browserName = 'chrome'
)
remDr$open()
remDr$navigate("insert URL here")
text_elements <- remDr$findElements("xpath", "//div/div/div/div[2]/div/span")
sapply(text_elements, function(x) x$getElementText()) %>%
unlist() %>%
as_tibble_col("results") %>%
filter(str_length(results) > 15)
# # A tibble: 6 × 1
# results
# <chr>
