如何使用 Selenium 和 Python 从 HTML 中提取文本

Question

我有这个HTML:

并且我想要得到这个文本“rataoriginal”。（这段文字有改动，我需要这部分代码作为文字）

我试过了

xpath = "//span[@class='_5h6Y_ _3Whw5 selectable-text invisible-space copyable-text']"
auxa = driver.find_element_by_xpath(xpath).text
print(auxa)

但它的打印结果与 print("\n") 相同。我暂时不想用 beaultifulsoup。

这个HTML来自'https://web.whatsapp.com'

Answer 1

//*[contains(text(),"rataoriginal")] 请使用这个 xpath

Answer 2

is a dynamic element, so to print the values you have to induce for the visibility_of_element_located() and you can use either of the following :

使用CSS_SELECTOR:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "span.selectable-text.invisible-space.copyable-text[dir='auto']"))).text)

使用XPATH:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//span[contains(@class, '') and contains(@class, 'invisible-space')][contains(@class, '') and @dir='auto']"))).text)

注意：您必须添加以下导入：

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