如何使用 Selenium Python 打印电子邮件地址

Question

<div id="MainCopy_ctl13_presentJob_EmailAddressPanel">
    <a id="MainCopy_ctl13_presentJob_EmailAddress" href="mailto:dburse@bjcta.org">xyzmmm@tccp.org</a>
</div>

我尝试过使用

email = browser.find_elements_by_xpath('//div[@id="MainCopy_ctl13_presentJob_EmailAddress"]//a').text
print(email)

但我没有得到结果。

Answer 1

a 标签内的 email 是 a 标签的 href，所以这样做：

使用硒：

from selenium import webdriver
    
driver = webdriver.Firefox()
driver.get("http://somedomain/url_that_delays_loading")


a_tag = driver.find_element_by_id('MainCopy_ctl13_presentJob_EmailAddress')
mail_link = a_tag.get_attribute("href")
mail_addrs = mail_link.split(':')[1]
print(mail_addrs)

使用 Beautifulsoup：

from bs4 import BeautifulSoup
    
content=""" 
<div id="MainCopy_ctl13_presentJob_EmailAddressPanel">
    a id="MainCopy_ctl13_presentJob_EmailAddress" href="mailto:dburse@bjcta.org">xyzmmm@tccp.org</a>
</div>"""
soup = BeautifulSoup(content)
a_tag = soup.find(id='MainCopy_ctl13_presentJob_EmailAddress')
mail_link = a_tag.attrs['href']
mail_addrs = mail_link.split(':')[1]
print(mail_addrs)

Answer 2

文本仅打印可见文本，对不在显示端口的文本使用 textContent 属性：

email = browser.find_element_by_xpath('//div[@id="MainCopy_ctl13_presentJob_EmailAddressPanel"]//a').get_attribute("textContent")
print(email)

Answer 3

元素已经存在了吗？或者在元素被 Selenium 加载之前执行的代码？

考虑使用等待：

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

driver = webdriver.Firefox()
driver.get("http://somedomain/url_that_delays_loading")
try:
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "myDynamicElement"))
    )
finally:
    driver.quit()

Answer 4

您使用的id属性，即MainCopy_ctl13_presentJob_EmailAddress属于<a>标签而不是<div>

要打印电子邮件地址，您可以使用以下任一Locator Strategies：

• 使用css_selector 和get_attribute()：

  print(driver.find_element(By.CSS_SELECTOR, "a#MainCopy_ctl13_presentJob_EmailAddress").get_attribute("innerHTML"))
  

• 使用xpath和text属性：

  print(driver.find_element(By.XPATH, "//a[@id='MainCopy_ctl13_presentJob_EmailAddress']").text)
  

---

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

• 使用CSS_SELECTOR和text属性：

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "a#MainCopy_ctl13_presentJob_EmailAddress"))).text)
  

• 使用XPATH 和get_attribute()：

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[@id='MainCopy_ctl13_presentJob_EmailAddress']"))).get_attribute("innerHTML"))
  

• 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
