How to get text in span with xpath. selenium python - python-3.x

Question

Before asking, I find answer through google for 2hours. But there's no answer for me.
I use selenium with python
I apply below q/a answer to my code but nothing text printed.
XPath query to get nth instance of an element
What I want to get is "Can't select"
<li data-index="5" date="20190328" class="day dimmed">
<a href="#" onclick="return false;">
<span class="dayweek">Tuesday</span>
<span class="day">28</span>
<span class="sreader">Can't select</span>
</a>
</li>
I use xpath because I need to repeat
I should do this.
The HTML code above is a simple change
day_lists = driver.find_elements_by_xpath('//li')
Nothing printed and there's no error
for day_list in day_lists:
print(day_list.find_element_by_xpath('//span[#class="sreader"]').text)
++++ 2019/3/24/16:45(+09:00)
When I test with below code
print(day_list.find_element_by_xpath('.//span[#class="sreader"]/text()'))
Error comes out. Why there's no such element?
selenium.common.exceptions.NoSuchElementException:
Message: no such element: Unable to locate element:
{"method":"xpath","selector":".//span[#class="sreader"]/text()"}

Answer 1

If nothing printed and there's no error then required text might be hidden or not generated yet.
For first case you might need to use get_attribute('textContent'):
day_lists = driver.find_elements_by_tag_name('li')
for day_list in day_lists:
print(day_list.find_element_by_xpath('.//span[#class="sreader"]').get_attribute('textContent'))
For second case:
from selenium.webdriver.support.ui import WebDriverWait as wait
day_lists = driver.find_elements_by_tag_name('li')
for day_list in day_lists:
print(wait(driver, 10).until(lambda driver: day_list.find_element_by_xpath('.//span[#class="sreader"]').text)
Note that in both cases you need to add leading dot in XPath:
'//span' --> './/span'

Answer 2

To print the desired text e.g. 선택불가 from the <span> tag you can write a function as follows:
def print_text(my_date):
print(driver.find_element_by_xpath("//li[#class='day dimmed'][#date='" +my_date+ "']//span[#class='sreader']").get_attribute("innerHTML"))
Now you can call the function with any date as follows:
print_text("20190328")

Answer 3

Here are the solutions. If this does not work then I predict the element might present either in separate window or frame.
CSS:
li[class='day dimmed'][date='20190328'] .sreader
xpath:
To check if there are multiple windows use below
print(len(driver.window_handles))
To check if there are multiple frames use below
print(len(driver.find_elements_by_css_selector('iframe')))

Answer 4

Try the following options:
day_lists=WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, '//li[#class="day dimmed"]')))
for day_list in day_lists:
print(day_list.find_element_by_xpath('//span[#class="sreader"]').text)
OR
day_lists=WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, '//li[#class="day dimmed"]')))
for day_list in day_lists:
print(driver.execute_script("return arguments[0].innerHTML;", day_list.find_element_by_xpath('//span[#class="sreader"]')))
Please note that you need following imports as well.
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
