How to click on nested href link using selenium python-CodePudding

Hi I'm fairly new to python and selenium and am having trouble accessing this href link. I was trying to access a href link by XPATH and am having trouble. My previous attempts at accessing an element by XPATH have worked just fine but i am having trouble accessing this specific href element

 WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH, "//body/div[@id='application']/div[@id='wrapper']/div[@id='main']/div[@id='not_right_side']/div[@id='content-wrapper']/div[@id='content']/div[@id='dashboard']/div[@id='DashboardCard_Container']/div[1]/div[1]/div[6]/div[1]/a[1]"))).click()
return driver

This is the error I am receving

    raise TimeoutException(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: 
Stacktrace:

this is the html file

I don't believe the element is inside an I frame and I believe I accessed the element correctly.

CodePudding user response：

WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH, "//body/div[@id='application']/div[@id='wrapper']/div[@id='main']/div[@id='not_right_side']/div[@id='content-wrapper']/div[@id='content']/div[@id='dashboard']/div[@id='DashboardCard_Container']/div[1]/div[1]/div[6]/div[1]/a[1]"))).click()

I think that the element's allocation is changing whenever the page reloaded..

CodePudding user response：

According to your html tree,each nested href link is unique by it's own class value. So you can grab it using class along with minizing xpath expression.

WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH, '//a[@]'))).click()
