我需要每5秒打印一次移动的文本,以下是html代码:
HTML:
<span class="cd-words-wrapper" style="width: 1170px;">
<b class="is-hidden">Test</b>
<b class="is-hidden">Test</b>
<b class="is-visible">Test</b>
<b class="is-hidden">Test</b>
</span>
我的Python代码:
Text = driver.find_elements_by_xpath(self.header)
time.sleep(5)
print(Text.text)
以上是获取文本的错误方法。请帮我解决这个问题。

如果您希望在新b
节点中出现文本后立即进行打印,请尝试以下代码:
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
while True:
text_node = WebDriverWait(driver, 10).until(visibility_of_element_located((By.CSS_SELECTOR, '.cd-words-wrapper > .is-visible')))
print(text_node.text)
WebDriverWait(driver, 10).until(lambda driver: text_node.get_attribute('class') == "is-hidden")
如果只想打印所有文本节点:
for text_node in driver.find_elements_by_css_selector('.cd-words-wrapper > b'):
print(text_node.get_attribute('textContent'))
