Question

我是selenium xpath的新手，这是我尝试过的代码。它根本不进入循环。我认为路径是正确的。有人可以帮忙吗？提前致谢。

a = driver.find_elements_by_xpath('//*[@class="one"]/ul/li')
for li in a:
     xval =  driver.find_element_by_xpath('.div/text()')`

<div class="one">
	<ul>
		<li><div id="1">Hi</div></li> 
		<li><div id="2"> Hello</div></li> 
		<li><div id="3">Bye</div></li> 
	</ul>
</div>

Answer 1

You can search child element by querying parent element. Also check the length of the parent element, does it have anything?

a = driver.find_elements_by_xpath('//*[@class="one"]/ul/li')
print len(a)
for li in a:
     xval =  li.find_element_by_xpath('div/text()')

Answer 2

In selenium find_element_by_xpath() method should return WebElement, but not text content.

Try to replace

xval = driver.find_element_by_xpath('.div/text()')

with

xval = driver.find_element_by_xpath('./div').text

Also note that you should use ./div instead of .div to match div that is direct child of current element

Update

If your loop make no iteration try to wait until required div appears in DOM as it might be generated dynamically:

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

WebDriverWait(driver, 10).until(EC.presence_of_element_located((By. XPATH, "//div[@class="one" and ./ul/li])))

在python中使用xpath检索列表元素
