How to wait for presence of an element with non empty content?

Question

How can I wait for a presence of an element which the content (text) is not empty? I tried select by xpath using //*[@id="test" and text() != ""], but the return of WebDriverWait#until does not retrieve the element.

My code:

selector = '//*[@id="test" and text() != ""]'
element = WebDriverWait(driver, timeout).until(
  expected_conditions.presence_of_element_located((By.XPATH, selector))
)

I would like to get the text content of the element. I tried:

print element.text # prints 0

If i print only element, the output is <selenium.webdriver.remote.webelement.WebElement(session="xxx", element="xxx")>. What is wrong?

The div I'm tryin to get has this structure:

<div>
   Test:
   <div id="test"><b>this text here</b></div>
</div>

You can wait for an element by xpath with non empty text like this:

xpath = "//*[@id='test']"

WebDriverWait(driver, 30).until(lambda driver: driver.find_element_by_xpath(xpath).text.strip() != '')
