rselenium

问题 "everything was better back then"... since firefox 49 (?) you can't use the rselenium package not straightforward anymore.

Like: download XY open AB so I can run code like the following require(RSelenium) remDr <- remoteDriver(remoteServerAddr = "localhost", port

问题 I'm trying to scrape data from website using RSelenium. I am able to navigate through drop downs individually but when I run them in loop I get error. Also after selecting all the values in the drop down I want to store the name of the facility and contact details in a table.

I'd like to pass as a function arguments the xpath expression and the environment into which the remote driver could be found library(RSelenium) url="http://stackoverflow.com/search?q=r+program" remdir<-remoteDriver(remoteServerAddr = "localhost", port = 4444, browserName = "firefox") remdir$open() remdir$navigate(url) env<-environment()

Please don't mark this as a duplicate. With respect to Firefox, I can't disable the dialog box. I've tried a number of different things. According to Firefox, the MIME type of the file I'm trying to download text/csv; charset=UTF-8 . However, executing the following code still elicits the dialog box to appear: fprof <-

问题 How can I navigate a dynamic drop down list via " using = 'id' " (e.g., remDr$findElement(using='id', value="main_ddYear") ? I can find and click using findElement . After clicking I could send "down arrow" keys (keystrokes) and an "enter" if I know how many arrows down my targeted selection is.

I have installed the RSelenium packages and I try to run it using this: library("RSelenium") #start RSelenium server startServer() checkForServer() and I receive this error: Error: checkForServer is now defunct.
