WebDriver UDF - Help & Support (IV)

[duke241]

And how I can add new attribute to an element? Thanks

[Danp2]

FWIW, the ability to remove an element was recently added to _WD_ElementActionEx by @SOLVE-SMART, and this functionality will be in the next release.

You are a very polite person @Danp2 😀 . Thanks for the credits - not necessary, but thanks 🤝 .

I hesitate to even to show my face in this topic since I am far from a programmer, and I basically learn by piecing together code from examples. However, I really would like to be able to automate Chrome, at least to a basic degree. I've been lurking for a while and have learned that the WebDriver udf is far above my pay grade of understanding, yet I keep coming back to it.

OK. here is what I would like to do.

Open Chrome with my own profile, go to any webpage and be able to extract the page's text to use in Regex....over and over again.

The script uses a loop and a middle-click trigger to do so. 

Hopefully, I am not too far out of my league with this. Thanks in advance.

Don't hesitate @fmendi 😀 , the most forum members are very helpful and polite.

Besides that your script is indeed incomplete, but not too bad. Can you please explain a bit further what do you mean by "Open Chrome with my own profile"? I saw your capabilities string with the user-data arg, but are you sure you want to do this?

Why? You described:

So a clean/default chromedriver instance could do the same thing. No need for your profile.

Thanks for the quick reply, Sven.

The reason I need to run Chrome under my profile is that the script will eventually be pretty long with auto log- ins to several websites as well as the use of a couple of chrome extensions.  

Below is  where $sText comes up nul.  Thanks....

Func MClick()
   $sElement = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "/html/body")
   $sText = _WD_ElementAction($sSession, $sElement, "text")
   MsgBox(1, "",$sText)     ; *******ERROR***********
EndFunc

I don't recommend sending data to the UDF with sendkeys. I also wouldn't recommend storing passwords in script files for any period of time, though that's a concern for later in the scripting process. When you want to fix that, try taking a look at KeePass.

As for how to use this UDF without copy/paste and sendkeys, I'd suggest getting really familiar these functions:
_WD_Navigate - Go to a URL
_WD_FindElement - Find a thing on a page, could be a username input in your case
_WD_ElementAction - Do a thing with that element you found, like setting the value to your username or clicking a button

When you get those figured out, you'll be able to do most of the basic stuff.

Your script is possibly breaking for a few reasons. I'm guessing though that you're not always creating the session since Chrome is already open. I suggest always creating a new instance and closing the old one when your script quits. Managing sessions is a pain IMHO

Thanks for the suggestions, seadoggie!

My plan was to start fresh by opening a chrome session under the umbrella of WebDriver and keeping it alive with the WEnd loop. I thought that the problem might be because of closing the original Chrome window  (WinClose("New Tab"), however, commenting that part out does not fix the problem. 

[CodeWriter]

@Danp2FYI, I have tried to use the method listed in WebDriver Wiki to utilize an existing profile in MS Edge without any success, namely:

$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"ms:edgeOptions": {"args": ["user-data-dir=C:\\Users\\' & @UserName & '\\AppData\\Local\\Microsoft\\Edge\\User Data\\", "profile-directory=Default"]}}}}'

This may be helpful for other users who have the same difficulty but after lots of experimentation, I found that the following capabilities string does work to launch MS Edge with an existing profile if you remove the "profile-directory" args and listing the chosen profile, e.g. "Profile 1" in this case:

$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"ms:edgeOptions": {"excludeSwitches": [ "enable-automation"], "args": ["user-data-dir=C:\\Users\\' & @UserName & '\\AppData\\Local\\Microsoft\\Edge\\User Data\\Profile 1"]}}}}'

And the corresponding method using @mLipok wd_capabilities.au3

_WD_CapabilitiesStartup()
    _WD_CapabilitiesAdd('alwaysMatch', 'msedge')
    _WD_CapabilitiesAdd('excludeSwitches', 'enable-automation')
    _WD_CapabilitiesAdd('args', 'user-data-dir=C:\\Users\\' & @UserName & '\\AppData\\Local\\Microsoft\\Edge\\User Data\\Profile 1')
    $sDesiredCapabilities = _WD_CapabilitiesGet()

If you agree, perhaps the Wiki suggested example could be amended.

[Danp2]

@CodeWriterThe existing method works for others, including me. I think the safest option is to add a comment explaining to replace "Default" as needed to the value shown in edge://version.

[CodeWriter]

@Danp2OK, but please include an explanation that dividing the profile path into 2 args: "user-data-dir=' and 'profile-directory=' will fail for some like me even when you replace "Default" with a specified profile "Profile 1".

[Danp2]

@CodeWriterThanks for the clarification as I didn't detect that from your earlier post. To clarify, you are saying that this works --

$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"ms:edgeOptions": {"args": ["user-data-dir=C:\\Users\\' & @UserName & '\\AppData\\Local\\Microsoft\\Edge\\User Data\\Profile 1"]}}}}'

but this doesn't work?

$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"ms:edgeOptions": {"args": ["user-data-dir=C:\\Users\\' & @UserName & '\\AppData\\Local\\Microsoft\\Edge\\User Data\\", "profile-directory=Profile 1"]}}}}'

If that's accurate, then I wonder if the space in the profile name is causing issues. 🤔

[CodeWriter]

Yes, the former works (but not with "Default"), and the latter does NOT work with any profile name ("Default" or otherwise). Not sure if the space is a factor because it is still present in the style that works.

Hi Dan,

could you be so kind and declare    $sDriverCurrent and  $sDriverLatest from _WD_UpdateDriver() as global in the next release? I need these vars in my program.

Thanks a lot

Hans

[Danp2]

@HJLThese are local variables to _WD_UpdateDriver, and they should remain local IMO. However, there are functions that allow you to retrieve these values yourself.

[SOLVE-SMART]

Hi @HJL,

I think this isn't necessary. You can get the WebDriver version like in wd_helper.au3 by:

Global $sCurrentWebDriverVersion = _WD_GetWebDriverVersion($sInstallDir, $sDriverEXE)

Also for the latest WebDriver info, you can use this:

Global $sLatestWebDriverInfo = __WD_GetLatestWebdriverInfo($aBrowser, $sBrowserVersion, $bFlag64)[1]

Best regards
Sven

If I would know how to do it I wouldn't ask 😉 But the solution is one thread above 😉

@HJLThe coding has already been done in _WD_UpdateDriver. You simply need to extract the relevant parts and use them in your own script. You can copy and paste, right? 😏
