Locate and activate hyperlink using RSelenium

My script below interacts with a Japanese geolocation website, successfully accesses a new page, but encounters issues locating and clicking on a specific link using RSelenium.

library(XML)
library(RSelenium)

remDr <- remoteDriver(
  remoteServerAddr = "localhost",
  port = 4445L,
  browserName = "firefox"
)

remDr$open()
remDr$navigate("https://maps.gsi.go.jp")
remDr$screenshot(display = TRUE)
remDr$getCurrentUrl()

webElem <- remDr$findElement(using = "id", value = "query")
webElem$getElementAttribute("id")
webElem$highlightElement()
webElem$sendKeysToElement(list("茨城県行方郡玉造町","\uE007"))
remDr$screenshot(display = TRUE)

I'm aiming to click on the node displayed below in order to extract the URL from the subsequent page. However, all my strategies involving remDr$findElement have proven ineffective. Could there be an essential step or approach that I am overlooking?

<a href="javascript:void(0);" style="padding-left: 32px; background: url(&quot;image/mapicon/search_result.png&quot;) 0px 50% no-repeat;"><div class="title">茨城県行方郡</div><div class="muni">茨城県行方市</div></a>

Answer №1

Is this the correct way?

element <- remDr$findElement(using = "css selector", value = ".city")
element$highlightElement()
element$clickElement()
remDr$getCurrentUrl()

Answer №2

When utilizing XPath :

remDr$navigate("https://maps.gsi.go.jp")
webElem <- remDr$findElement(using = "xpath","//input[@id='query']")
webElem$clickElement()
webElem$sendKeysToElement(list("茨城県行方郡玉造町", key = "enter"))

webElem2 <- remDr$findElement(using = "xpath","//div[@class='searchresultdialog_ul_frame']//a")
webElem2$clickElement()

In case of encountering errors, you can utilize a while/Trycatch combination (all credit to @Victor Burnett) to ensure the element's presence is waited for.
