<span class="cname"><em class="multiple">2017</em> Ford 
</span>
<span class="cname">Toyota
</span>

I want to get only "FORD" and TOYOTA in span.

test.find_element_by_class_name('cname').text

return "2017 FORD" and "TOYOTA". So how can i get particular text of span?

Pure XPath solution:

//span[@class='cname']//text()[not(parent::em[@class='multiple'])]

And if you alse want to filter white-space-only text-nodes():

//span[@class='cname']//text()[not(parent::em[@class='multiple']) and not(normalize-space()='')]

Both return text-nodes not an element. So Selenium will probably fail. Take a look here: https://sqa.stackexchange.com/a/33097 on how to get a text-node(). Otherwise use this answer: https://stackoverflow.com/a/67518169/3710053

EDIT:

Another way to go is this XPath:

//span[@class='cname']

And then use this code python-example to get only direct text()-nodes.

EDIT 2

all_text = driver.find_element_by_xpath("//span[@class='cname']").text
child_text = driver.find_element_by_xpath("//span[@class='cname']/em[@class='multiple']").textparent_text = all_text.replace(child_text, '')
