docs-internal-guid-049ac94a-f34e-5729-b053-30567fdf050a docs-internal-guid-765e48e9-f34b-7c88-5d95-042a93fcfda3 what's best approach? find , copy each id not viable. thanks
edit: can use following script retrieve star restaurants:
library("rvest") url_base <- "http://www.straitstimes.com/lifestyle/food/full-list-of-michelin-starred-restaurants-for-2017" data <- read_html(url_base) %>% html_nodes("h3") %>% html_text() this gives headers ("one michelin star", "two michelin stars", "three michelin stars"), bu might helpful.
background script: fortunately, , relevant information within h3 selector. script gives char vector output. of course, can further elaborate on e.g. %>% as.data.frame() or want store / process data.
------------------- old answer -------------------
could maybe provide url of particular page? me sounds have find right css-selector (nth-child(x)) can use in loop.
