NoSuchElementException selecting cell value based on header name by xpath

Question

I would like to select a cell value with a known row index and selecting it by header name (here "Adjusted Amount")

My code is as follows:

driver.find_element(By.XPATH, value = f"/html/body/form[2]/table/tbody/tr/td/table/tbody/tr[{2}]/td[th[text()='Adjusted Amount']]/input").get_attribute('value')

but still get a NoSuchElementException.

Answer 1

Given the HTML:

There are a couple of issues in your line of code which you need to address as follows:

• The element with text Adjusted Amount is within an <iframe> so you have to induce WebDriverWait for the desired frame_to_be_available_and_switch_to_it.

   WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe#WorkArea")))
  

• The element with text Adjusted Amount isn't within any <th> but within <td>. So to reference the <td> element ideally you need to induce WebDriverWait for the visibility_of_element_located() and you can use the following locator strategies:

• Using CSS_SELECTOR:

  WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "form[name*='TotalBondCalculation table table > tbody > tr td:nth-child(7)']")))
  

• Using XPATH:

  WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//form[contains(@name, 'TotalBondCalculation')]//table//table/tbody/tr//td[text()='Adjusted Amount']")))
  

• 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
