A lightweight implementation of w3c webdriver specification


seleniumPipes is a lightweight implementation of the w3c webdriver specification. It has been built utilising xml2, httr and magrittr so provides an alternative for users who are familiar with piping.


To install seleniumPipes from CRAN


To install the current developement version of seleniumPipes run:


Getting started

The easiest way to start is to look at the Basic operations vignette:

Failing this a few basic examples are presented below:

Get started using seleniumPipes you can look at the following example

library(RSelenium) # start a server with utility function
selServ <- RSelenium::startServer()
remDr <- remoteDr()
remDr %>% go(url = "")
remDr %>% go(url = "")
remDr %>% back()
remDr %>% forward()
remDr %>% refresh()
remDr %>% go("") %>% getPageSource()
# {xml_document}
# <html>
# [1] <head>\n<title>The Comprehensive R Archive Network</title>\n<meta content="text/html; charset=u ...
# [2] <frameset style="border: none;" cols="1*, 4*">\n<frameset rows="120, 1*">\n<frame frameborder=" ...

remDr %>% getPageSource() %>% xml_find_all("//frame") %>% xml_attr("name")
# [1] "logo"     "contents" "banner"  

remDr %>% deleteSession()


Piping in seleniumPipes is achieved using the pipe operator from magrittr%>%`:

remDr %>% go("") %>% 
  findElement("name", "q") %>% 
  elementSendKeys("R project", key = "enter")

Functions relating to the remote driver which would not be expected to return data can be expected to return the remote driver. Functions relating to a web element which would not be expected to return data can be expected to return the web element. This allows chaining of commands as shown above.

Further examples are available on install in the examples directory.

Builtin retry of Endpoints

remDr <- remoteDr()
webElem <- remDr %>% go("") %>% 
  findElement("name", "q")

# change the name of q with an 8 second delay
myscript <- "var myElem = arguments[0]; window.setTimeout(function(){
}, 8000);"
remDr %>% executeScript(myscript, args = list(webElem))

newWebElem <- remDr %>% findElement("name", "funkyname")

# > newWebElem <- remDr %>% findElement("name", "funkyname")
# Calling  findElement  - Try no:  1  of  3 
# Calling  findElement  - Try no:  2  of  3 

newWebElem %>% getElementAttribute("name")
