如何在python selenium中查找元素的标题

Question

<div> <div class="alk_dvImage"><a href="/products/"><img class="alk_prImg" src="https://a random photo" alt="a random product"></a> </div> <div class="product-score"></div> <a href="/products/" class="alk_prName alk_pr" title="Products Title">Strong Graphic Card </a> </div>

Answer 1

会发生什么

如果没有在选择器中按点链接类，请尝试以下操作：

browser.find_element_by_css_selector('a.alk_prName.alk_pr').get_attribute("title")

示例：

from selenium import webdriver
browser = webdriver.Chrome('C:\Program Files\ChromeDriver\chromedriver.exe')

html_content = """
  <a href="/products/" class="alk_prName alk_pr" title="Products Title">Strong Graphic Card</a>
"""

browser.get("data:text/html;charset=utf-8,{html_content}".format(html_content=html_content))

browser.find_element_by_css_selector('a.alk_prName.alk_pr').get_attribute("title")

Answer 2

要打印标题属性的值，即产品标题，可以使用以下任一Locator Strategies：

• 使用css_selector：

  print(driver.find_element(By.CSS_SELECTOR, "a.alk_prName.alk_pr[href='/products/']").get_attribute("title"))
  

• 使用xpath：

  print(driver.find_element(By.XPATH, "//a[@class='alk_prName alk_pr' and @href='/products/'][contains(., 'Strong Graphic Card')]").get_attribute("title"))

理想情况下，您需要为visibility_of_element_located()诱导WebDriverWait，并且您可以使用以下任一Locator Strategies：

• 使用CSS_SELECTOR：

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "a.alk_prName.alk_pr[href='/products/']"))).get_attribute("value"))
  

• 使用XPATH：

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[@class='alk_prName alk_pr' and @href='/products/'][contains(., 'Strong Graphic Card')]"))).get_attribute("value"))
  

• 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
