I am trying to extract information from a webpage that shows distances between cities by car, by inserting the cities from Excel cells into the webpage, then extracting the resulted distance back into Excel.
I was not able to click the button on the following webpage via normal FindElementByClass or Id or whatever.
Here is the link in text form: https://gps-online.webshow.ro/planificator-rute.html
Here is the link in link form:
So I asked ChatGPT to provide alternatives, and JavaScript injection was golden! Also, extracting the text with XPath was a great solution and finally, using RegEx to extract the number from the text, simplified things in Excel.
The code below can be improved of course, for example to go through a range of cities and extract distances between them, but this is the simple - Selection wise - way to go:
Sub Extract_Routes()
' FIRST: Set a reference to Selenium Type Library (Tools > References > Selenium Type Library)
Dim driver As New WebDriver
Dim url As String
url = "https://gps-online.webshow.ro/planificator-rute.html"
' Start a new Edge browser session and wait 2 secons for the page to load
driver.Start "Edge", ""
driver.Get url
driver.Wait 2000
Dim rng As Range
Set rng = Selection
Dim c1, c2 As String
c1 = rng.Offset(0, 1).Text
c2 = rng.Offset(0, 2).Text
' Insert data from cells into "plecare" and "sosire" fields
driver.FindElementById("plecare").SendKeys (c1)
driver.FindElementById("sosire").SendKeys (c2)
' Use JavaScript injection to click the button by its text
driver.ExecuteScript "document.querySelector('button[onclick=""generateRoute()""]').click();"
driver.Wait 3000 ' Wait for 3 seconds, otherwise there will be an "Out of memory" error
' Find the <p> element containing the distance text using XPath
Dim distanceElement As WebElement
Set distanceElement = driver.FindElementByXPath("//div[@id='directions-step-by-step']//p[contains(text(), 'Distanta:')]")
If Not distanceElement Is Nothing Then
distanceText = distanceElement.Text
' Extract the numeric value using regular expressions
Dim regex As Object
Set regex = CreateObject("VBScript.RegExp")
regex.Global = True
regex.IgnoreCase = True
regex.Pattern = "\d+(?:\.\d{3})*" '"\d+" ' Match one or more digits
' Find and print the numeric value
If regex.test(distanceText) Then
Dim matches As Object
Set matches = regex.Execute(distanceText)
Dim numericValue As String
numericValue = Replace(matches(0).Value, ".", ",")
' Print the first match (the numeric value)
' Debug.Print matches(0).Value
rng.Offset(0, 3).Value = numericValue
Else
Debug.Print "Numeric value not found."
End If
Else
Debug.Print "Distance text not found."
End If
driver.Quit
End Sub |
