rvest

问题 I am using the R rvest library to read an html page containing tables. Unfortunately the tables have inconsistent number of columns. Here is an example of the table I read: <table> <tr class="alt"> <td>1</td> <td>2</td> <td class="hidden">3</td> </tr> <tr class="tr0 close notule"> <td colspan="9">4</td> </tr> </table> and my code to read the table in R: require(rvest) url = "table.html" x <- read_html(url) (x %>% html_nodes("table")) %>% html_table(fill=T) # [[1]] # X1 X2 X3 X4 X5 X6 X7 X8 X9

问题 I am trying to piece together how rvest is used, and I thought I'd got it but all the results I receive are null. I am using @RonakShah 's example (Loop with rvest) as my base example and thought I'd try and expand to instead collect the name, telephone and hours open each day: site = "https://concreteplayground.com/auckland/bars/archie-brothers-cirque-electriq" get_phone <- function(url) { webpage <- site %>% read_html() name <- webpage %>% html_nodes('p.name') %>%html_text() %>% trimws()

I can get that by using the below code. I have a csv file that cycles through the dates and then binds them together. How can I extract the data between the div tags and then bind it together with

问题 This is as follow up to my previous question here: How to extract contents between div tags with rvest and then bind rows The page that I am trying to extract the data from between the div tags is from this site: http://bigbashboard.com/rankings/batsmen This is a different page to my previous question (although it is still the same site). The key difference is that the dates that appear in the URL are only displayed as year/month like so: http://bigbashboard.com/rankings/batsmen/2020/10 as
