WebDriver UDF - Help & Support (IV)

[noellarkin]

PS: (sorry for the duplicate post)  is there any way to get  the chromedriver to work with Ungoogled Chromium instead of Google Chrome? Which Global variable should I change?

[Danp2]

I haven't used NppExec, so I can't provide much guidance there. I can only speculate that something is different in the way that it launches AutoIt. Have you checked the working directory in each scenario?

To use an alternative browser, you will need to supply the binary location of the browser executable as part of your capabilities string.

[iSan]

I had read your Web Driver, but did not see detail guide, i have some questions please answer them for me:

I want to clear then fill value in input. I knew that i miss many thing in this code, i'm newbie

Autoit:

Func _Run()

   $sSession = _WD_CreateSession(Default)
   ; Locate a single element
   ; (Global Const $sElementSelector = "//input[@class='UserName']")
   $sElement = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, $sElementSelector)

   _WD_ElementAction($sSession, $sElement, 'clear')
   Sleep(500)
  
   _WD_ElementAction($sSession, $sElement, 'value', "testing 123")
   Sleep(500)
   
EndFunc

Html:

<input class="UserName" id="LoginExtender_txtUserName" onkeypress="$find('LoginExtender')._keypress(this, event);" autocomplete="off" style="width: 275px">

Then get this:

__WD_Post ==> Send / Recv error [6] : HTTP status = 0
_WD_CreateSession ==> Webdriver Exception [10]
__WD_Post ==> Send / Recv error [6] : HTTP status = 0
_WD_FindElement ==> Send / Recv error [6] : Parameters:   Strategy=xpath   Selector=//input[@class='UserName']   StartNodeID=Default   Multiple=Default   ShadowRoot=Default
__WD_Post ==> Send / Recv error [6] : HTTP status = 0
_WD_ElementAction ==> Send / Recv error [6] : Parameters:   Command=clear   Option=Default
__WD_Post ==> Send / Recv error [6] : HTTP status = 0
_WD_ElementAction ==> Send / Recv error [6] : Parameters:   Command=value   Option=<masked>

You can't use Default here. You need to pass a valid string containing the requested capabilities. Take a look at the functions starting with "setup" (SetupGecko, SetupChrome, etc) in wd_demo for some example strings.

[iSan]

In case that i use only Chrome for 

_WD_FindElement

and 

_WD_ElementAction

[Danp2]

@iSanNo idea what you are trying to say. Are you able to run wd_demo successfully? 🤔

[iSan]

I got Error: Check logs. I only test for DemoElements

@Danp2 I'm sorry, i mean that i use only Browser: Chrome and i wanna find, clear, input or click to an Element. 

I know that i can use _WD_FindElement, _WD_ElementAction

But i'm getting confuse, how to SetChrome as default.

Ex Demo: Default browser is Chrome then DemoElemnts

Is that understandable? Sorry for my bad English

[Danp2]

@iSan If you check the scite output panel,  you will find the reason for the check logs message.  it's probably because you haven't downloaded chromedriver. The script will download it for you if you choose the correct option from the Update drop down.

For your own script, you should be able use the SetupChrome routine from wd_demo.

[iSan]

Oh. The script actually download it for me, i can rune Demo now.

But what does Headless (Yes/No) do? Can i skeep it and set Headless = False

yes you can skip this setting (keep it to False), otherwise you will not see what your browser automation doings will do (or not do) 😅 .

Please have a look at the README file of the project to get more information and to get more into the WebDriver approach. I'm sure this will help you a lot. Also get in touch with the Tutorial/Wiki page of the project. There are several answered question which will help you 😀 .

It would also be helpful when you talk about what are you trying to do? I noticed you want to clear and fill a input. Are you able to navigate to the page and are you able to use locators/selectors like XPath or CSS Selector etc.? If not, I recommend you to learn more about that before.

Please provide that much information as you can. Then it's probably that we can support you on your way of browser automation 🤝 .

Best regards
Sven

Try to build my scrip:

; non standard UDF's
#include "wd_helper.au3"
#include "wd_capabilities.au3"
#include "wd_core.au3"
#EndRegion - include files

Local  $sCapabilities, $sSession

_SetupChrome()

_WD_Startup()
$sSession = _WD_CreateSession($sCapabilities)
_WD_Navigate($sSession, 'https://www/youtube.com')
_WD_SetInputValue($sSession, "//input[@id='search']", 'test input')
_WD_ClickElement($sSession, "//button[@id='search-icon-legacy']")

Func _WD_SetInputValue($sSession, $xPath, $Value)
    $Element = _WD_FindElement($sSession, 'xpath', $xPath)
    _WD_ElementAction($sSession, $Element, 'value', $Value)
EndFunc

Func _WD_ClickElement($sSession, $xPath)
    $Element = _WD_FindElement($sSession, 'xpath', $xPath)
    _WD_ElementAction($sSession, $Element, 'Click')
EndFunc

Func _SetupChrome()
    _WD_Option('Driver', 'chromedriver.exe')
    _WD_Option('Port', 9515)

Please update your WinHTTP source using the link above.

Quote

__WD_Post ==> Invalid argument [5] : HTTP status = 400 _
WD_CreateSession ==> Webdriver Exception [10]

Your attempt to create a session is failing. It appears that you are declaring $sCapabilities local to SetupChrome, so the value assigned is lost once that function exits.

[iSan]

@Danp2 I'm using WinHTTP:   1.6.4.1 now, that is not the problem. The thing is that i declared $sCapabilities local to SetupChrome, i just add Return $sCapabilities in _SetupChrome then it works. Now i improve my scrip. Thank you so much and...

Happy new year!!!

 

[Danp2]

@iSanGlad you got the initial kinks worked out. A few suggestions --

• As previously mentioned, you should update WinHTTP to avoid some know issues that can occur with v1.6.4.1
• Add some error checking to your custom functions. For example, if _WD_FindElement returns an error then it makes no sense to continue with call to _WD_ElementAction

[DoVinhTrung]

Hi @Danp2,i have code u can see help me if i open  1 file exe run with chromedriver.exe and open 2 file will chromedriver 1 wiil cloe. i set : 

G lobal $_WD_DRIVER_CLOSE = False ; Close prior driver instances before launching new one

Global $_WD_DRIVER_DETECT = False ; Don't launch new driver instance if one already exists

Global $_WD_RESPONSE_TRIM = -1 ; Trim response string to given value for debug output

Global $_WD_ERROR_MSGBOX = False ; Shows in compiled scripts error messages in msgboxes

 

and set in my code

 

_WD_Option('Driver', 'chromedriver.exe')

_WD_Option('Port', 9515)

_WD_Option('DriverParams', '--verbose --log-path="' & @ScriptDir & '\chrome.log"')

_WD_Option('DriverClose',False)

 

 

still close chromedriver 1

[Danp2]

@DoVinhTrungThe following two lines of code perform the same action --

_WD_Option('DriverClose',False) 
 
$_WD_DRIVER_CLOSE = False

While you can modify the global variables directly, using _WD_Option to access / modify these variables is the recommended method.

You may want to check the chome.log file to see if it gives the reason for one of the chromedriver instances closing. You haven't provided enough details to know for sure, but it could be because you aren't using a unique port number combination for each set of Chrome / Chromedriver.

I suggest that you review this prior thread.

Please advise which library to use to work with Xpath.
I am currently using WebDriver UDF to read a table of 100 rows and 12 columns and query each cell <td> via :

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

There are 2 queries per cell. This is slow and inefficient.
I want to take the whole table into memory with the command

$sTable = _WD_ElementAction($sSession, $sElementIdTable, 'property', 'outerHTML')

and extract <tr> and <td> from $sTable.
Is there a library that handles string variables via Xpath?
It would be very convenient to change the code so that it leaves the search keys for Xpath exactly the same as for WD_FindElement($WD_SESSION, $_WD_LOCATOR_ByXPath, ....).
Can you please suggest a library with the closest syntax in terms of Xpath?

PS _WD_GetTable cannot be used. as I am retrieving different objects from the same cell. And _WD_GetTable glues all the text into one value and I can't separate it into its components.
Thank you!
 

[SOLVE-SMART]

Hi @dadLog,

can you share the DOM structure of your table? Then it is probably more easy to recommend a better XPath instead what you are trying to do 🤞 .

How this will look like? Please show your data, DOM etc., thanks 🤝 .

    </div>
</td>

Output: City-1, Data-1, City-2, Data-2, Number -1,2,3,4,5 and "Comment, strings"

Other <td> very simple -

<td>data1</td>

<td>
    data2
    <span>data2</span>
</td>

Thank you, Sven! )

Thanks @dadLog.

Hmm, you only need the values of the <span> tags inside the <td> tags, am I right?
Is it a public page (URL) or can you share more of the DOM? The whole <table> structure would be nice. Then I could try it on my own.

Best regards
Sven
