time.sleep(5)
while True:
    for elem in driver.find_element(By.XPATH,('.//span[@class="tiktok-zsq8pw-SpanChatRoomComment ex6o5349"]')).text:
        print(elem,end="")

How i am gonna pass the next element in body or any solution?

Answer 1

In order to iterate over several elements you have to use find_elements instead of find_element and extract the text prom each element during the iteration over the list. Also your while loop is bad there.
So your code could be something like the following:

driver.get("http://tiktok.com/@"+username+"/live")
time.sleep(5)
for elem in driver.find_elements(By.XPATH,('.//span[@class="tiktok-zsq8pw-SpanChatRoomComment ex6o5349"]')):
    print(elem.text)
