I have the following HTML:
<h3><a href='jobdetail.php?job=705945'>Job Details</a>: lrp1_vs_Hx1sh2</h3><h4>
With this code, I tried to extract the element value lrp1_vs_Hx1sh2
library(RSelenium)
webpage <- "https://cluspro.bu.edu/models.php?job=705945"
browser <- remoteDriver(port = 5556)
browser$open()
browser$navigate(webpage)
clk <- browser$findElement(using = "link text", "Use the server without the benefits of your own account")
clk$clickElement()
jobs <- browser$findElement(using = 'link text', "Job Details")
jobs$getElementText()
But it gives me "Job Details" instead.
How can I do it correctly?
Update
THis is the full HTML:

CodePudding user response：
You can use this xpath
//div[@id='main-header-right']//following-sibling::h3
that should fetch all the text inside that h3 tag.
once you have the text, try to split the text based on space. Then you can choose the appropriate splitted text-based out of the index.
CodePudding user response：
Locating element by link text "Job Details" gives you the a element while you need to get the h3 element text.
Try this instead:
jobs <- browser$findElement(using = 'xpath', "//h3[contains(@href,'jobdetail.php?job=705945')]")
jobs$getElementText()
Or in case the job id can be changing try this:
jobs <- browser$findElement(using = 'xpath', "//h3[contains(@href,'jobdetail.php')]")
jobs$getElementText()
