我无法使用Python / Selenium单击网页中的任何元素

Question

I'm webscrapping this webpage: https://www.skoob.com.br/o-pequeno-principe-693ed56597.html but for some reason I can't click anything an I don't know why.

I've tried to use both implict and explicit wait, find element by xpath and text. It just doesn't work.

for l in range(1, 107):
    wait.until(EC.element_to_be_clickable((By.XPATH, '//*[@id="estante"]/div[3]/div['+str(l)+']/a/img')))
    driver.find_element_by_xpath('//*[@id="estante"]/div[3]/div['+str(l)+']/a/img').click()

    driver.find_element_by_link_text('Leitores').click()

I've tried by text and it's giving me timeoutexception. NoSuchElementException sometimes. Also clicking with pyautogui doesn't work, Python actually seems to ignore the pyautogui line.

The element you described in your post vs. in your comment don't appear to be the same thing. Here's how I would implement a simple wait and click:

public void ElementExists(this IWebDriver driver, By by)
{
    try
    {
        // element exists, so return true
        return driver.FindElements(by).Count > 0;
    }
    catch (NoSuchElementException e)
    {
        // element does not exist so return false
        return false;
    }
}

// use ElementExists in this method
public void WaitForElementToExist(this IWebDriver driver, By by)
{
    // initialize wait to 30 seconds
    var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30));
    wait.Until(d => d.ElementExists(by);
}

// lastly -- wait and click
public void WaitForElementAndClick(this IWebDriver driver, By by)
{
    driver.WaitForElementToExist(by);
    driver.FindElement(by).Click();
}

With this code implementation, you can accomplish what you are trying to achieve like this:

driver.WaitForElementAndClick(By.XPath("//a[text()='2.856']"));

This will wait for the element to exist & click it, based on the HTML sample you provided in your comment.
