How to find elements that do not include a certain class name with selenium and python

Question

I want to find all the elements that contain a certain class name but skip the ones the also contain another class name beside the one that i am searching for

I have the element <div class="examplenameA"> and the element <div class="examplenameA examplenameB">

At the moment i am doing this to overcome my problem:

items = driver.find_elements_by_class_name('examplenameA')
for item in items:
    cname = item.get_attribute('class')
    if 'examplenameB' in cname:
        pass
    else:
        rest of code

I only want the elements that have the class name examplenameA and i want to skip the ones that also contain examplenameB

To find all the elements with class attribute as examplenameA leaving out the ones with class attribute as examplenameB you can use the following solution:

css_selector:

items = driver.find_elements_by_css_selector("div.examplenameA:not(.examplenameB)")

xpath:

items = driver.find_element_by_xpath("//div[contains(@class, 'examplenameA') and not(@class='examplenameB')]")

You can use xpath in this case. So as per your example you need to use something like driver.find_elements_by_xpath('//div[@class='examplenameA'). This will give you only the elements whose class is examplenameA

So how xpath works is : Xpath=//tagname[@attribute='value']

Hence the class is considered as the attribute & xpath will try to match the exact given value, in this case examplenameA, so <div class="examplenameA examplenameB"> will be ignored

In case of find_elements_by_class_name method, it will try to match the element which has the class as examplenameA, so the <div class="examplenameA examplenameB"> will also be matched

Hope this helps
