要验证所需文本是否存在于任何元素中，您需要使用引发的 try-catch {} 块用于 text_to_be_present_in_element()的WebDriverWait ，您可以使用以下

To validate the presence of the desired text within any element you need to use a try-catch{} block inducing WebDriverWait for text_to_be_present_in_element() and you can use either of the following Locator Strategies:

• 使用 CSS_SELECTOR :

try:
    WebDriverWait(driver, 20).until(EC.text_to_be_present_in_element((By.CSS_SELECTOR, "div.ui-dialog-content.ui-widget-content#dialog>pre"), "Text is here"))
    print("Desired text was present")
except TimeoutException:
    print("Desired text was not present")

try:
    WebDriverWait(driver, 20).until(EC.text_to_be_present_in_element((By.XPATH, "//div[@class='ui-dialog-content ui-widget-content' and @id='dialog']/pre"), "Text is here"))
    print("Desired text was present")
except TimeoutException:
    print("Desired text was not present")
