  • You're saying that you want to filter elements by id and at the same time later you're saying that you have class attribute and you want to filter by class. – wec Nov 8 at 13:49

Python has a feature called List Compreenshion, aimed at creating lists from other lists, after applying some processing on each element.

1 - Find the li elements:

li_items = driver.find_elements_by_class_name("li")

2 - Filter in only element with a given class:

li_items_with_class = [ item for item in list_items if "my_class" in item.get_attribute("class")]

item for item => Simply add the item on the results

in list_items => From this list

if "my_class" in item.get_attribute("class") => If this item has "my_class" on the "class" attribute

This can be done with extra filtering in Python, but the usual straightforward way is to add an extra condition to your CSS selector:

all_items = driver.find_elements_by_css_selector("ul > li")

versus:

filtered_items = driver.find_elements_by_css_selector("ul > li.myclass")

where . is a class selector.
