RSelenium & Web Scraping
I'm trying to scrape data but I'm having trouble scraping it. I'm able to navigate through website using RSelenium. You can find my code below. I want to scrape names from each drop down so that I can store them in an object and run a loop.
library(RSelenium)
library(rvest)
library(XML)
library(RCurl)
rd<-rsDriver()
remDr<-rd[["client"]]
url<-"https://kvk.icar.gov.in/facilities_list.aspx"
jsScript <- "var element = arguments[0]; return element.outerHTML;"
webpage<-read_html(url)
remDr$navigate("https://kvk.icar.gov.in/facilities_list.aspx")
remDr$refresh()
#First drop down
stateEle<-remDr$findElement("id", "ContentPlaceHolder1_ddlState")
#webElem <- remDr$findElement("id", "ContentPlaceHolder1_ddlDistrict")
stateHTML <- remDr$executeScript(jsScript, list(stateEle))[[1]]
statedoc <- htmlParse(appHTML)
states<-doc["//option", fun = function(x) xmlGetAttr(x, "name")]
stateEle$clickElement()
stateEle$sendKeysToElement(states[[30]])
stateEle$clickElement()
#Second drop down
distEle<-remDr$findElement("id", "ContentPlaceHolder1_ddlDistrict")
distHTML <- remDr$executeScript(jsScript, list(distEle))[[1]]
distdoc <- htmlParse(appHTML)
districts<-doc["//option", fun = function(x) xmlGetAttr(x, "value")]
distEle$clickElement()
distEle$sendKeysToElement(list(distdoc[[2]]))
distEle$clickElement()
#Third drop down
kvkEle<-remDr$findElement("id", "ContentPlaceHolder1_ddlKvk")
appHTML <- remDr$executeScript(jsScript, list(kvkEle))[[1]]
kvkdoc <- htmlParse(appHTML)
kvk<-doc["//option", fun = function(x) xmlGetAttr(x, "value")]
kvkEle$clickElement()
kvkEle$sendKeysToElement(list(kvk[[2]]))
kvkEle$clickElement()
#submitting the values
submitEle<-remDr$findElement("id", "ContentPlaceHolder1_btnSubmit")
submitEle$clickElement()
Also I want to scrape the results into a dataframe.

You could try just clicking on the select list, withoutvalue =
part, and sending the first few keys of your value (sayANDAMAN
). Note that the value you want should be highlighted, then sendEnter
key. For this you will want to read aboutsendKey
functionality of Selenium.

Using your code,
stateEle<-remDr$findElement("id", "ContentPlaceHolder1_ddlState")
From here, if you want to get all values to do the looping, use:
library(magrittr)
stateEle$getElementText()[[1]] %>% strsplit(., '\n')
This will provide a list of text elements, where you could further remove the "--Select--"
option:
stateEle$getElementText()[[1]] %>% strsplit(., '\n') %>% unlist %>% setdiff(., '--Select--')
Repeat this for all other select lists.
So I am able to loop through all the the drop downs. But in the end I am having problem in scraping the data after a page opens. @Nutle
