Selenium scraping
selecting multiple elements using xpath is not a good idea. You can look into "css selector". Using this you can get similar elements.
I am trying to come up with a way to scrape information on houses on Zillow and I am currently using xpath to look at data such as rent price, principal and mortgage costs, insurance costs. 
I was able to find the information using xpath but I wanted to make it automatic and put it inside a for loop but I realized as I was using xpath, not all the data for each listing has the same xpath information. for some it would be off by 1 of a list or div. See code below for what I mean. How do I get it more specific? Is there a way to look up for a string like "principal and interest" and select the next value which would be the numerical value that I am looking for?
works for one listing:
driver.find_element_by_xpath("/html/body/div[1]/div[6]/div/div[1]/div[1]/div[1]/ul/li[1]/article/div[1]/div[2]/div")
a different listing would contain this:
driver.find_element_by_xpath("/html/body/div[1]/div[6]/div/div[1]/div[1]/div[2]/ul/li[1]/article/div[1]/div[2]/div")
