我如何 select selenium 中没有 ID/text_link/name 的元素？

Question

HTML of the website

The HTML code of the element I want to select:

   <a href="../s-reminderNotice.asp?fname=b%2D3c%2DpLessonBooking%2Easp%3Flimit%3Dpl" class="sidelinkbold" 
   target="mainFrame" 
   onmouseover=" window.status='Practical Training Booking'; 
   return true" onmouseout="window.status=' ';
   return true">Booking without Fixed Instructor</a>

I would like to select the element of this "Booking without Fixed Instructor"; however there isn't an ID/link_text/name for this element. How can I direct the site to the HREF. Is there a way to use xpath to locate it, the element is in the column on the left of the website so there are many other elements of the same class. (see pic.)

I tried this and it returned:

AttributeError: 'WebDriver' object has no attribute 'findElement'

Code:

driver.findElement(By.xpath("//a[@href='THE LINK']")).click();

SOLVED; ELEMENT WAS IN AN IFRAME; HAD TO SWITCH FRAME TO ACCESS ELEMENT

Answer 1

AttributeError: 'WebDriver' object has no attribute 'findElement'

you are using python so driver dowsn't have findElemnt method, it is find_Element

https://www.selenium.dev/selenium/docs/api/py/webdriver_remote/selenium.webdriver.remote.webdriver.html?highlight=webdriver%20class#selenium.webdriver.remote.webdriver.WebDriver.find_element_by_class_name

use:

    driver.find_element(By.XPATH("//a[contains(string(),'Booking without Fixed Instructor')]")

Answer 2

To click on the element with text as Booking without Fixed Instructor you can use either of the following Locator Strategies :

• Using link_text :

   driver.find_element(By.LINK_TEXT, "Booking without Fixed Instructor")

• Using partial_link_text :

   driver.find_element(By.PARTIAL_LINK_TEXT, "Booking without Fixed Instructor").click()

• Using css_selector :

   driver.find_element(By.CSS_SELECTOR, "a.sidelinkbold[href*='s-reminderNotice']").click()

• Using xpath :

   driver.find_element(By.XPATH, "//a[@class='sidelinkbold' and contains(@href, 's-reminderNotice')][contains(., 'Booking without Fixed Instructor')]").click()

The desired element is a dynamic element, so ideally to click on the element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies :

• Using LINK_TEXT :

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.LINK_TEXT, "Booking without Fixed Instructor"))).click()

• Using PARTIAL_LINK_TEXT :

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.PARTIAL_LINK_TEXT, "Booking without Fixed Instructor"))).click()

• Using CSS_SELECTOR :

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a.sidelinkbold[href*='s-reminderNotice']"))).click()

• Using XPATH :

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='sidelinkbold' and contains(@href, 's-reminderNotice')][contains(., 'Booking without Fixed Instructor')]"))).click()

• Note : You have to add the following imports:

   from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC

You can find a couple of relevant discussions on NoSuchElementException in:

• selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element while trying to click Next button with selenium
• selenium in python: NoSuchElementException: Message: no such element: Unable to locate element

Answer 3

Try this xpath:

//a[text()[contains(.,'Booking without Fixed Instructor')]]
