使用 selenium xpath 定位元素

Locate an element using selenium xpath

我正在尝试在 chrome 检查代码 <href="app/arp/home/profile">.

中找到具有以下行的元素

我的台词是:

driver.find_element(By.xpath("//a[@href='/app/arp/home/profile']")).click()

但我收到以下错误:

AttributeError: type object 'By' has no attribute 'xpath'

怎么了?

请试试这个

driver.find_element_by_xpath("//a[@href='/app/arp/home/profile']")

AttributeError: type object 'By' has no attribute 'xpath'.

这意味着您没有导入正确的对象By

确保在页面顶部添加 import

from selenium.webdriver.common.by import By 

直到 v3.141.0 to locate an element using 您可以使用以下语法:

driver.find_element_by_xpath("//a[@href='/app/arp/home/profile']")

但是,在即将发布的版本中 find_element_by_* commands will be deprecated

def find_element_by_xpath(self, xpath):
    """
    Finds an element by xpath.

    :Args:
     - xpath - The xpath locator of the element to find.

    :Returns:
     - WebElement - the element if it was found

    :Raises:
     - NoSuchElementException - if the element wasn't found

    :Usage:
        ::

            element = driver.find_element_by_xpath('//div/td[1]')
    """
    warnings.warn("find_element_by_* commands are deprecated. Please use find_element() instead")
    return self.find_element(by=By.XPATH, value=xpath)
        

从 Selenium v4.x 开始,有效语法将是:

driver.find_element(By.XPATH, "//a[@href='/app/arp/home/profile']")

一个例子:

  • 代码块:

    from selenium import webdriver
    from selenium.webdriver.common.by import By
    
    driver.get("https://www.google.com/")
    element = driver.find_element(By.NAME, "q")
    print(element)
    driver.quit()
    
  • 控制台输出:

    <selenium.webdriver.remote.webelement.WebElement (session="04a9fac269c3a9cb724cc72769aed4e0", element="1b8ee8d0-b26a-4c67-be10-615286a4d427")>
