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, without value = part, and sending the first few keys of your value (say ANDAMAN). Note that the value you want should be highlighted, then send Enter key. For this you will want to read about sendKey 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.
