I had this pop out box stated with "no such element error". I really don't know what's wrong with the code. This basic code is actually looking up for the search box and input text which is ABC. I hope I can find someone who can kindly guide me. Your help will be very much appreciated. TQ

NoSuchElementException is one of the different WebDriver Exceptions and this Exception occurs, when the locators (i.e. id / xpath/ css selectors etc) we mentioned in the Selenium Program code is unable to find the web element on the web page. There are two possibilities for getting this Exception, i.e. either we have provided a incorrect locator and trying to find the web element or we have provided correct locator, but the web element related to the locator is not available on the web page.
Please try using the below
XPATH
//input[#placeholder='Search for an item']
CSS SELECTOR
input[placeholder='Search for an item']
Note: Put some waits while locating to the element, as I do not know in Vba, but in java like below
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(30));
WebElement elem = wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//input[#placeholder='Search for an item']")));
elem.sendKeys("ABC");
Hope this answer your question

WinAppDriver's FindElement will not always find objects in the program to be automated.
I've gotten this to work with other programs, like Notepad, and even a different dialog in my program to be automated, and it worked in those places.
This is the code I am using so far. The first three lines execute without error, successfully launching the application into it's Login dialog:
Dim appCapabilities As DesiredCapabilities = New DesiredCapabilities()
appCapabilities.SetCapability("app", "C:\[my program].exe")
Dim ProgramSession = New WindowsDriver(Of WindowsElement)(New Uri("http://127.0.0.1:4723"), appCapabilities)
ProgramSession.FindElementByName("Password").SendKeys("Password")
The fourth line should find the element, a text box, and enter the string "Password" into it via sendkeys, but it fails, with the following exception:
System.InvalidOperationException: 'An element could not be located on the page using the given search parameters.'
The target object is on screen, and this should work. I'm using the info shown for the object in Inspect.exe, Name: "Password".
WinAppDriver's window shows the following error information:
{"using":"name","value":"Password"}
HTTP/1.1 404 Not Found
Content-Length: 139
Content-Type: application/json
{"status":7,"value":{"error":"no such element","message":"An element could not be located on the page using the given search parameters."}}
The fourth line of code is executed directly after program startup.
Since a program needs some load time, you'll need to wait for the program to finish loading before trying to search for a control on the GUI. You can do this by using a while loop in combination with a stopwatch for timeout.
Dim shouldContinue As Boolean = True
Dim stopWatch As StopWatch = New StopWatch()
Dim timeOut As TimeSpan = TimeSpan.FromSeconds(30)
stopWatch.Start()
While shouldContinue AndAlso timeOut > stopWatch.Elapsed
If element.IsFound Then
shouldContinue = False
stopWatch.Stop()
End If
End While
element.IsFound is just mock-up code, you will need to fill in that blank. This is a good Q/A to show you how to check if a element has loaded.
Another thing you need to take in account is the possibility that your Login Dialog runs in another window handle. If the window handle winappdriver is using is different from the window handle where your element is at, you won't be able to find that element.
Also check if you can find whatever you are searching for in the PageSource property xml from your driver. I usually do this by calling that property in the visual studio watch window, and copying it's content to a xml formatter tool.
I was able to find the password field by using FindElementByXPath instead of FindElementByName.
In order to find the xpath, I used the Recorder for WinAppDriver.
These xpaths can be VERY long. I was able to shorten some of them by removing some duplicate attributes, but some are over 450 characters long. I can sometimes reduce it further with variables, but I'm not exactly delighted so far with WinAppDriver as a replacement for CodedUI.
I have written a macro in Excel that opens and parses a website and pulls the data from it. The trouble I'm having is once I'm done with all of the data on the current page I want to go to the next page. To do this I want to get the last child of the "result-stats" node. I found the lastChild function, and so came up with the following code:
'Checks to see if there is a next page
If html.getElementById("result-stats").LastChild.innerText = "Next" Then
html.getElementById("result-stats").LastChild.Click
End If
And here is the HTML that it is accessing:
<p id="result-stats">
949 results
<span class="optional"> (1.06 seconds)</span>
Modify search
Show more columns
Next
</p>
When I try to run this, I get an error. After a lot of searching I think I found the reason. According to what I read, getElementById returns an element and not a node. lastChild only works on nodes, which is why the function doesn't work here.
My question is this. Is there a clean and simple way to grab the last child of an element? Or is there a way to typecast an element to that of a node? I feel like I'm missing something obvious, but I've been at this way longer than I should have been. Any help anyone could provide would be greatly appreciated.
Thanks.
Here's a shell of how to do it. If my comments are not clear, ask away. I assumed knowledge of how to navigate to the page, wait for the browser, etc.
Sub ClickLink()
Dim IE As Object
Set IE = CreateObject("InternetExplorer.Application")
'load up page and all that stuff
'process data ...
'click link
Dim doc As Object
Set doc = IE.document
Dim aLinks As Object, sLink As Object
For Each sLink In doc.getElementsByTagName("a")
If sLink.innerText = "Next" Then 'may need to play with this, if `innerttext' doesn't work
sLink.Click
Exit For
End If
Next
End Sub
I'm getting an error "Object doesn't support this property or method"
Below is my coding,
Dim webs, web As Object
Set webs = driverg.findElementByCssSelector("*[class^='title-link id-track-click']")
**For Each web In webs**
Debug.Print web.Text
Next web
When program starts in foreach, I'm getting this error.
Is there any another method looping Web-element as I have tried a lot, but I can't solve this?
You've defined webs as a Variant
By putting them on same line it doesn't default to the declaration at the end
Define them on their own separate lines
Dim webs As Object
Dim web As Object
Or if that's not what you intended and web is an array then use
Dim webs As Object
Dim web As Variant
EDIT - check docs
According to docs - it only returns the first element - so I'm not sure why you're doing a "For each"
Type: IWebElement The first IWebElement matching the criteria.
I have changed findElementByCssSelector into findElementsByCssSelector, as findElementByCssSelector return only one element hence that for each not wroking but when changed into findElemenstByCssSelector, getting working.
I have changed below line
driverg.findElementByCssSelector("*[class^='title-link id-track-click']")
to
driverg.findElementsByCssSelector("*[class^='title-link id-track-click']")
Or how to work with collections (or arrayss) in VBA.
The issue is most probably myself, but I couldn't find an answer yet.
I am trying to go trough a some pages on a web-site with Selenium-vba to find some data.
As usual if there is more to display, the site shows a 'NEXT' button. The button has <a href ... > when the link is activated, else it's just plain text.
To test if there is another page I have found the way to use findElementsByLinkText, and either there is a link or the the collection is empty. So this can be tested by the size of the collection.
This works so far.
But when I try to use the collection (aside from a for each loop) for further action I can't get it to operate.
This is the code:
Dim driver As New SeleniumWrapper.WebDriver
Dim By As New By, Assert As New Assert, Verify As New Verify, Waiter As New Waiter
On Error GoTo ende1
driver.Start "chrome", "http://www.domain.tld/"
driver.setImplicitWait 5000
driver.get "//......."
Set mynext = driver.findElementsByLinkText("Next")
if mynext.Count >0 Then
mynext(1).Click 'THIS STATEMENT DOES NOT WORK
End If
So please help me to get around my understanding issue (which I am convinced it is)
How can I access an element from the collection.
My workaround so far is to execute
driver.findElementByLinkText("Next").Click
but this is unprofessional as it executes the query again.
The Next button is probably loaded asynchonously after the page is completed.
This implies that findElementsByLinkText("Next") returns no elements at the time it's called.
A way to handle this case is to silent the error, adjust the timeout and test the returned element:
Dim driver As New Selenium.ChromeDriver
driver.Get "https://www.google.co.uk/search?q=selenium"
Set ele = driver.FindElementByLinkText("Next", Raise:=False, timeout:=1000)
If Not ele Is Nothing Then
ele.Click
End If
driver.Quit
To get the latest version in date working with the above example:
https://github.com/florentbr/SeleniumBasic/releases/latest
My attempts at writing a simple crawler seem to be confounded by the fact that my target webpage (as would appear in the UI browser control, or through a typical browser application) is not completely accessible as an HTMLDocument (due to frames, javascript, etc.)
The code below executes, and the correct webpage (e.g. the one displaying items 50-59) can even be seen in the control, but where I would expect the “next page” hyperlink retrieved to be “...&start=60”, I see something else – the one corresponding to opening the first catalog page “...&start=10”.
What is odd, is that if I press the button a second time, I DO get what I’m looking for. Even odder to me, if I inserted a MsgBox, say right after I’ve looped to wait until WebBrowserReadyState.Complete, then I get what I’m looking for.
Private Sub ButtonGo_Click(sender As System.Object, e As System.EventArgs) Handles ButtonGo.Click
'start at this URL
'e.g. http://www.somewebsite.com/properties?l=Dallas+TX&co=US&start=50
catalogPageURL = TextBoxInitialURL.Text
WebBrowser1.Navigate(catalogPageURL)
While WebBrowser1.ReadyState <> WebBrowserReadyState.Complete
Application.DoEvents()
End While
'Locate the URL associated with the NEXT>> hyperlink
Dim allLinksInDocument As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("a")
Dim strNextPgLink As String = ""
For Each link As HtmlElement In allLinksInDocument
If link.GetAttribute("className") = "next" Then
strNextPgLink = link.GetAttribute("href")
End If
Next
End Sub
I’ve googled around enough to try things like using a WebBrowser1.DocumentCompleted
event, but that still didn’t work. I’ve tried inserting sleep commands.
I’ve avoided using WebClient and regular expressions, the way I would have ordinarily done this, because I’m convinced using the DOM will be easier for other things I have planned down the road, and I’m aware of HTML Agility Pack but not ambitious enough to learn it. Because it seems there has to be a simple way to have this dang webbrowser.document object synchronized with the stuff you can actually see.
If this is because of javascript, is there a way I can tell the webbrowser to just execute them all?
First question on the forum, looking forward to more (smarter ones hopefully)
Be warned when using webbrowser1.Document or something similar - you will not get 'raw html'
Example: (assume wbMain is a webbrowser control)
RTB_RawHTML.Text = wbMain.DocumentText
Try
RTB_BodyHTML.Text = wbMain.Document.Body.OuterHtml
Catch
debugMessage("Body tag not found.")
End Try
in this example, the code in the body tag as displayed in the body tag portion of RTB_RawHTML will NOT perfectly match the html as displayed in RTB_BodyHTML. Accessing it through (yourwebbrowserhere).Document.Body.OuterHtml appears to 'clean' it somewhat as opposed to the 'raw' html as retreived by (yourwebbrowserhere).DocumentText
This was a problem for me when i was making a web scraper, as it would continually throw me off - sometimes i would try to match a tag and it would find it, and other times it wouldnt even though i was sure it was there. The reason was that i was trying to match the raw html, but i needed to match the 'cleaned' html.
Im not sure if this will help you isolate the problem or not - for me it did.
