Xpath to locate element using text() and @class as conditions

I am trying to automate adding items to cart in online shop, however, I got stuck on a loop that should differentiate whether item is available or not.

Here's the loop:

while True:
        #if ???
            WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.XPATH, "//*[text()='" + size.get() + "']"))).click()
            sleep(1)
            WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.XPATH, "//*[text()='Add to cart']"))).click()
            sleep(1)
            print("Success!")
            break
        else:
            driver.refresh()
            sleep(3)

If the size is available, button is active:

<div class="styles__ArticleSizeItemWrapper-sc-dt4c4z-4 eQqdpu">
    <button aria-checked="false" role="radio" class="styles__ArticleSizeButton-sc-1n1fwgw-0 jIVZOs">
        <span class="styles__StyledText-sc-cia9rt-0 styles__StyledText-sc-1n1fwgw-2 styles__ArticleSizeItemTitle-sc-1n1fwgw-3 gnSCRf cLhSqA bipwfD">XL</span>
        <span class="styles__StyledText-sc-cia9rt-0 ffGzxX">
        </span>
    </button>
</div>

If not, button is inactive:

<div class="styles__ArticleSizeItemWrapper-sc-dt4c4z-4 eQqdpu">
    <button disabled="" aria-checked="false" role="radio" class="styles__ArticleSizeButton-sc-1n1fwgw-0 fBeTLI">
        <span class="styles__StyledText-sc-cia9rt-0 styles__StyledText-sc-1n1fwgw-2 styles__ArticleSizeItemTitle-sc-1n1fwgw-3 gnSCRf cLhSqA bipwfD">XXL</span>
        <span class="styles__StyledText-sc-cia9rt-0 styles__StyledText-sc-1n1fwgw-2 kQJTJc cLhSqA">
        </span>
    </button>
</div>

The question is: what should be the condition for this loop?

I have tried something like this:

if (driver.find_elements(By.XPATH, "//*[contains(@class='styles__ArticleSizeButton-sc-1n1fwgw-0 jIVZOs') and text()='" + e2.get() + "']")):

EDIT: Replaced "=" with "," in the above code as follows:

if (driver.find_elements(By.XPATH, "//*[contains(@class='styles__ArticleSizeButton-sc-1n1fwgw-0 jIVZOs') and text()='" + e2.get() + "']")):

but I keep getting invalid xpath expression error.

EDIT: The error is gone, but the browser keeps refreshing with the else statement (element not found).

I believe your error is in the use of the contains function, which expects two parameters: a string and a substring, although you're passing it a boolean expression (@class='styles__ArticleSizeButton-sc-1n1fwgw-0 jIVZOs').

I expect this is just a typo and you actually meant to type contains(@class, 'styles__ArticleSizeButton-sc-1n1fwgw-0 jIVZOs') (NB comma instead of an equals sign after @class).

Also, you are looking for a button element which has a child text node (text() refers to a text node) which is equal to the size you're looking for, but that text node is actually a child of a span which is a child of the button. You can compare your size to the text value of that span.

Try something like this:

"//*[contains(@class='styles__ArticleSizeButton-sc-1n1fwgw-0 jIVZOs') and span='"
+ e2.get() 
+ "']"

e3="Some value"
x=f"//button[contains(@class,'styles__ArticleSizeButton-sc-1n1fwgw-0 jIVZOs') and not(contains(@disabled='')) and ./span[contains(text(),'{e3}')]])]"
print(x)

Try looking for the button which contains that class and with that span and maybe check if button disabled?

I managed to get it working using this condition:

if (driver.find_elements(By.XPATH,
 "//*[contains(@class, 'styles__ArticleSizeButton-sc-1n1fwgw-0 jIVZOs')
 and .//*[text()='" + e2.get() + "']]")):

It is quite similar to the original approach, however, adding .//* before text() did the trick.

Without .//* find_elements was looking in the same node which resulted in not finding the element. .//* instructs find_elements to look in the child node where element exists.

Important: text condition was wrapped in additional [] brackets.
