使用Selenium在Python中循环遍历XPath元素位置

Question

How can I loop through element positions in Python using Selenium?

I've tried this and it's not working:

for i in range(2,21):
    un = browser.find_element_by_xpath("(//div[@class='cname'])[i]").text
    print(un)

Answer 1

You have to format your string to put inside i value:

for i in range(2,21):
    un = browser.find_element_by_xpath("(//div[@class='cname'])[{0}]".format(i)).text
    print(un)

Answer 2

As per your code block an alternative would be to to use find_elements_by_xpath along with the index [i] as follows :

for i in range(2,21):
    un = browser.find_elements_by_xpath("//div[@class='cname']")[i].text
    print(un)
