You don't need an array in this case. However, 

Local $sElement = _WD_WaitElement($sSession, $_WD_LOCATOR_ByXPath, '//*[@id="mat-tab-label-0-0"]/div/span/app-number-viewerapp', 100, 5000)
Local $sText = _WD_ElementAction($sSession, $sElement, 'property', 'innerText')

MsgBox(0, "Total", $sText)

on one PC I get such error:

Anybody hit the problem ?

EDIT: As so far I found:

https://github.com/mozilla/geckodriver/issues/550

https://github.com/mozilla/geckodriver/issues/1208

But in my case it looks like this is not a FIREWALL problem, but I can be wrong.

Found solution.
In order to solve this issue I had to modify _WD_StartUp() by adding --port parameter to the command :

Local $sCommand = StringFormat('"%s" %s ', $_WD_DRIVER, $_WD_DRIVER_PARAMS & " --port=" & $_WD_PORT )

 

EDIT:
Should we add this as a default fix to wd_core.au3 ?

@mLipokDon't change _WD_Startup. You should Instead use _WD_Option to add that setting if needed. For example --

$iAltPort = 4567
_WD_Option('DriverParams', '--log trace --port=' & $iAltPort)
_WD_Option('Port', $iAltPort)

P.S. You didn't provide enough details for us to know if you are using the standard port number or a different one. 😏

so I suggest to modify _WD_Startup() in this way:

;~  Local $sCommand = StringFormat('"%s" %s ', $_WD_DRIVER, $_WD_DRIVER_PARAMS)
    If Not StringInStr($_WD_DRIVER_PARAMS, "--port") Then $_WD_DRIVER_PARAMS &= " --port=" & $_WD_PORT
    Local $sCommand = StringFormat('"%s" %s ', $_WD_DRIVER, $_WD_DRIVER_PARAMS)

Because if user specify port by this:

_WD_Option('Port', $iAltPort)

then it should be no need to again set the option (port) by this:

_WD_Option('DriverParams', '--log trace --port=' & $iAltPort)

 

I mean it is redundant _WD_Option() usage, because when it is set once, it should be set properly, so this:

_WD_Option('Port', $iAltPort)

should be the only one needed.

 

Can you agree with my reasoning ?

Edited November 11, 2022 by mLipok

[Danp2]

@mLipokIf you are not using the default port for webdriver communication, then you must notify the webdriver of the alternate port. This is what is occurring in the 'DriverParams' line.

I understand why you want to make this change. However, I believe that it isn't needed as the vast majority scripts will use the default port number. Also, the following is valid for geckodriver and your change could lead to unexpected results --

_WD_Option('DriverParams', '-p ' & $iAltPort)

This issue has definitely come up previously, so this could make a good FAQ.

Have anyone tried Google calendar? It seems it can not find anything with _WD_FindElement

it would return something like this

__WD_Post: URL=HTTP://127.0.0.1:9515/session/147c20d2cde2adb344f3397afad8cda8/element; $sData={"using":"xpath","value":"//div[@role='button']"}

is the page source code encrypted? It seems what the program gets is not what we see in f12 developing window.

 

@Danp2any comments? please help, thanks.

The above shows that the element was in fact found. Now you need to do something with it. What's your next step. Do you need to click it, retrieve its value, or something else?

try to click it. but why it's so different?

[Danp2]

@jiataifengYes, webdriver can take some getting used to. Don't concern yourself with the JSON string being returned. It's simply a GUID that webdriver uses to identify the element. Just make sure the request succeeded (check @error) and then proceed with your next step.

You may want to check out the section on the wiki that discusses transitioning from IE.

@Danp2

When available, could you take a look of Google Calendar? I don't know how to set the value of the highlighted part, though tried for a very long time. Thank you

Edited November 30, 2022 by jiataifeng

[mLipok]

Did you try JS ?

[Danp2]

@jiataifengI took a quick look, but didn't see an immediate solution. SelectorsHub reported that it is inside a Shadowroot, but I didn't see it when I checked. 🤷‍♂️

Hello!
Please, help with _WD_FindElement() , parameter $sStartNodeID 
I could not find an example in wd_demo.au3

You must use a relative selector when using xpath with a starting node. You also need to obtain the element's text separately.

Instead of this --

$sTd1 = _WD_FindElement($WD_SESSION, $_WD_LOCATOR_ByXPath, "/tr/td[1]/span/text()" , $idElem )

You need to do it like this --

$idElem = _WD_FindElement($WD_SESSION, $_WD_LOCATOR_ByXPath, "./td[1]/span" , $idElem)
        $sContents = _WD_ElementAction($WD_SESSION, $idElem, 'text')

Another option would be to use _WD_GetTable to obtain an array containing the table's contents.

[dadLog]

Danp2 - you are divine!
Thanks for the tip about _WD_GetTable , I used it, but because of the complex cell contents I need individual access to each cell. 
You have solved my problem.
Thank you so much!

After updating geckodriver.exe to 0.32.0 I'm getting the following error:

__WD_Post ==> Webdriver Exception [10] : HTTP status = 500 ResponseText={"value":{"error":"session not created","message":"Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line","stacktrace":""}}

 

Also, I usually run scripts with SciTE-Lite, but I've been playing around with Notepad++ NppExec as well - - when I run any webdriver related scripts with NppExec I get the following error:

_WD_Startup ==> File issue [18] : Non-existent Web Driver: geckodriver.exe

I don't get this error with SciTE-Lite. What could be the reason? I've only had this issue with anything related to geckodriver.exe. I have geckodriver.exe in PATH.

[Danp2]

@noellarkinIIRC, this occurs with the 32 bit version of Geckodriver. You need to either switch to the 64 bit version or supply the binary location as part of your capabilities string.

This feature was added by @mLipokhere. The current implementation requires you to either provide the full path to the webdriver or it must exist in the current working directory. Unsure why it works in one editor and not the other.

[noellarkin]

I was able to get it working by moving the geckodriver.exe to the Include folder, as well as using the x64 version. Thanks for clarifying.
However, the SciTE/Notepad++ issue remains, still getting "Non-existent Web Driver: geckodriver.exe " when using NppExec.
