IWebElement firstButton = wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("//a[@class='FBYjn gK0xL A7Cr_ m3ODJ']")));

IWebElement firstButton = wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("//a[@class='FBYjn gK0xL A7Cr_ m3ODJ']")));

i am using Chrome the thing is, it clicks buttons with only 1 word in its class

Angius•4w ago

IIRC XPath doesn't have anything like "a list of classes"

SilentRocket7478OP•4w ago

what does that mean ? that is how the html looks

Angius•4w ago

Sure

SilentRocket7478OP•4w ago

<button type="button" class="FBYjn gK0xL A7Cr_ m3ODJ"></button>

<button type="button" class="FBYjn gK0xL A7Cr_ m3ODJ"></button>

Angius•4w ago

But I don't think XPath supports multiple classes in a @class

SilentRocket7478OP•4w ago

what can i do then?

Angius•4w ago

Maybe //a[contains(@class, 'FBYjn') and contains(@class, 'gK0xL') and contains(@class, 'A7Cr_') and contains(@class, 'm3ODJ')]?

SilentRocket7478OP•4w ago

div? where u get //div from?

Angius•4w ago

Well, a in your case There, fixed

SilentRocket7478OP•4w ago

it is a button, not "a"

Angius•4w ago

SilentRocket7478OP•4w ago

should i replace it?

Angius•4w ago

//a[contains(concat(' ',normalize-space(@class),' '),' FBYjn gK0xL A7Cr_ m3ODJ ')] could also work

SilentRocket7478OP•4w ago

i think i used wrong code wait should there be even //a ?

Angius•4w ago

If you want to match an anchor tag, then yes

SilentRocket7478OP•4w ago

it is a button we are talking about, as you know, maybe.

Angius•4w ago

//button then, not //a

SilentRocket7478OP•4w ago

alright then how is it looking?

//button[contains(@class, 'FBYjn') and contains(@class, 'gK0xL') and contains(@class, 'A7Cr_') and contains(@class, 'm3ODJ')]

//button[contains(@class, 'FBYjn') and contains(@class, 'gK0xL') and contains(@class, 'A7Cr_') and contains(@class, 'm3ODJ')]

Angius•4w ago

Try it

SilentRocket7478OP•4w ago

Angius•4w ago

There are XPath checkers out there

SilentRocket7478OP•4w ago

what does that mean? now i got this

IWebElement firstButton = wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("//button[contains(@class, 'FBYjn') and contains(@class, 'gK0xL') and contains(@class, 'A7Cr_') and contains(@class, 'm3ODJ')]")));

IWebElement firstButton = wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("//button[contains(@class, 'FBYjn') and contains(@class, 'gK0xL') and contains(@class, 'A7Cr_') and contains(@class, 'm3ODJ')]")));

looking good?

Angius•4w ago

I'd say so

Angius•4w ago

The online XPath tester says it's good:

This free online XPath tester lets you test your expressions/queries against an XML file

SilentRocket7478OP•4w ago

it still does not click, like it does not finds it

Angius•4w ago

Debug, then

SilentRocket7478OP•4w ago

Looking for the first button... Created TensorFlow Lite XNNPACK delegate for CPU. Error: Timed out after 30 seconds ChromeDriver closed. i did dotnet debug dotnet run everytime even when i do most minor things i am not sure if i must to but i am a bit new to C hashtag

Angius•4w ago

There's no dotnet debug command

SilentRocket7478OP•4w ago

in visual studio code

Angius•4w ago

Place a breakpoint on the line that's supposed to get the element, and see if you actually get it Then step through the code and see where it goes

SilentRocket7478OP•4w ago

the small red dot?

Angius•4w ago

Yes

SilentRocket7478OP•4w ago

ok and then i run it?

Angius•4w ago

With the debug profile, yes $debug

SilentRocket7478OP•4w ago

ok nothing happens i added a breakpoint i ran i did debug ofcourse but won-t click lemme show ya this

Angius•4w ago

If the code did not stop at the breakpoint, that means the code did not run So maybe you're not calling the method or something

SilentRocket7478OP•4w ago

Console.WriteLine("Looking for the first button...");

IWebElement firstButton = wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("//button[contains(@class, 'FBYjn') and contains(@class, 'gK0xL') and contains(@class, 'A7Cr_') and contains(@class, 'm3ODJ')]")));

Console.WriteLine($"First button found. Text: {firstButton.Text}, Location: {firstButton.Location}, Size: {firstButton.Size}");

Console.WriteLine($"First button found. Text: {firstButton.Text}, Location: {firstButton.Location}, Size: {firstButton.Size}");

Angius•4w ago

Does Looking for the first button... show in the console?

SilentRocket7478OP•4w ago

yes

Angius•4w ago

I guess your debugging went wrong, then Alas, I don't have much experience writing and debugging C# in VSCode

SilentRocket7478OP•4w ago

i will try the code in visual studio

Angius•4w ago

Ideally, that's what you should be using, yeah

SilentRocket7478OP•4w ago

so i moved everything there but the problem is still there i tried to click another button that has only 1 class it worked fine i do not know what is its trouble with more than 1 class buttons

Angius•4w ago

Try the other XPath I posted

SilentRocket7478OP•4w ago

Angius•4w ago

Or... instead of By.XPath try By.CssSelector("button.FBYjn.gK0xL.A7Cr_.m3ODJ") Or By.ClassName("FBYjn gK0xL A7Cr_ m3ODJ"), but this lets you select only by, well, classes

SilentRocket7478OP•4w ago

haha the first one not productive Looking for the first button... Unexpected error: Compound class names not allowed. Cannot have whitespace in class name. Use CSS selectors instead.; For documentation on this error, please visit: https://www.selenium.dev/documentation/webdriver/troubleshooting/errors#invalid-selector-exception ChromeDriver closed. is it worth to mention that the button in inside a div ?@Angius

Angius•4w ago

What of By.CssSelector?

SilentRocket7478OP•4w ago

? what? both did not work

Angius•4w ago

Does this one work?

SilentRocket7478OP•4w ago

Angius•4w ago

Could maybe try ByAll And chain multiple ByClassName like that

SilentRocket7478OP•4w ago

nope it produces an error it dose not exist in this context

Angius•4w ago

new ByAll(By.ClassName(...), By.ClassName(...)) Highly recommend reading the docs

SilentRocket7478OP•4w ago

i think i will look into it tomorrow im so tired my eyes are closing between each message i appreciate your time i will definitly update you

Angius•4w ago

:Ok:

ckam03•4w ago

Man I feel for you It's simple for xpath //div[@class='FPdoLc lJ9FBc'] That's how you add multiple classes for cssselector By.CssSelector("textarea[class='gLFyf']")) also just need a space if you have a button inside of a div then you would do something like //center//input[@class='gNO89b'] I recommend using css selectors though with a cssSelector, the previous selector would be center > input[class='gNO89b'] all you need is a space between classes XPath needs an @ before class while cssSelector doesn't

SilentRocket7478OP•4w ago

@ckam03What if it was a button inside tons of divs? is it possible to click the button directly?

ckam03•4w ago

yes just keep adding div > div > div if you have to or //div//div//div I've had selectors like 10 elements deep before Do you really need that though? There's usually a better way than having to go 10 elements deep. Is there no id or anything?

SilentRocket7478OP•3w ago

I got it fixed
