Hi, everybody!

I did a robot that run procedures on a website. But, I face 04 page configurations, as follow:

nav.find_element_by_xpath('/html/body/div[1]/div/div[3]/div[1]/div/div[2]/div/div/span[1]/p[1]')
nav.find_element_by_xpath('/html/body/div[1]/div/div[3]/div[1]/div/div[2]/div/div/span[1]/p[2]')
nav.find_element_by_xpath('/html/body/div[1]/div/div[3]/div[1]/div/div[2]/div/div/span[1]/p')
nav.find_element_by_xpath('/html/body/div[1]/div/div[3]/div[1]/div/div[2]/div/div/span[1]')

It happens because I get into many pages, and the text that I need to check are sometimes in one of those 04 cases. In this way, I declared all of them.

But, I got the error below, because it get into in a page and the second XPATH simply does not exists. But, the program closes and do not run.

So, does anyone know how can I check if that object exists before try to use it?

Thanks!

The error message is that:

You can wrap your code into try/except clause, e.g.

from selenium.common.exceptions import NoSuchElementException
# ... 
try:
    nav.find_element_by_xpath('/html/body/div[1]/div/div[3]/div[1]/div/div[2]/div/div/span[1]/p[1]')
except NoSuchElementException:
    pass # or do something

Thanks!!
