Selenium scrapes only one result and ignores other related reults - python-3.x

Question

I am new to selenium. Searching a web site, I get 10 results for each page. Those results are shown as lists (li tags) on the page and each list contains the same attributes. When my conditions are met, I go to another related web page and get desired content. However, when my code keeps looping for the lists, it fails to find the same attributes for the others. Here is my code:
p_url = "https://www.linkedin.com/vsearch/f?keywords=BARCO%2BNV%2Bkortrijk&pt=people&page_num=5"
driver.get(p_url)
time.sleep(5)
results = driver.find_element_by_id("results-container")
employees = results.find_elements_by_tag_name('li')
#emp_list = []
#for i in range(len(employees)):
# emp_list.append(employees[i])
for emp in employees:
try:
main_emp = emp.find_element_by_css_selector("a.title.main-headline")
name = emp.find_element_by_css_selector("a.title.main-headline").text
href = main_emp.get_attribute("href")
if name != "LinkedIn Member":
location = emp.find_element_by_class_name("demographic").text
href = main_emp.get_attribute("href")
print(href)
print(location)
driver.get(href)
exp = driver.find_element_by_id("background-experience")
amkk = exp.find_elements_by_class_name("editable-item")
for amk in amkk:
him = amk.find_element_by_tag_name("header").text
him2 = amk.find_element_by_class_name("experience-date-locale").text
if '\n' in him:
a = him.split('\n')
print(a[0])
print(a[1])
print(him2)
except Exception as exc:
print(exc)
continue
In this code the line main_emp = emp.find_element_by_css_selector("a.title.main-headline") stop working after it works for the first time. As a result I got an error of Message: stale element reference: element is not attached to the page document
From stackoverflow questions I saw that some say the content is removed from DOM structure and from another post someone suggested to fill a list with the results. Here what I have tried emp_list = []
for i in range(len(employees)):
emp_list.append(employees[i]) , however, it also did not work out.
How can I overcome this?

Answer 1

The selector you are using is wrong. You are getting the results using the results-container id. This works fine, but the collecting the elements form this is not working. It is returning more elements than just the employees (I'm not quite sure why).
If you change you selectors to this single selector you will get just the employees and no other unwanted elements.
employees = results.find_elements_by_css_selector("ol[id='results']>li")
Edit
Since you are opening the employees and losing the list of elements you might want to try opening the employee in a new tab, perform your actions here and close the tab afterwards.
Example:
for emp in employees:
try:
main_emp = emp.find_element_by_css_selector("a.title.main-headline")
# Do stuff you need...
# Open employee in new tab (make sure Keys is imported)
main_emp.send_keys(Keys.CONTROL + 't')
# Focus on new tab
driver.switch_to_window(d.window_handles[1])
# Do stuff inside the employee page
# Close the tab you opened
driver.close()
# Switch back to the first tab
driver.switch_to_window(d.window_handles[0])
Note: For OSX you should use main_emp.send_keys(Keys.COMMAND + 't')
