Question

我试图从“data-nice-url”元素中获取属性，我的html看起来像这样：

<div class="car-thumb-item clickable vehicle " data-include_settings="true" data-nice_url="/privatleasing/Citro%c3%abn-Berlingo/eHDi-90-Seduction-E6G" data-id="34285" style="display: block;">
<div class="car-thumb-brand">Citroën</div>
<div class="car-thumb-model">Berlingo </div>
<div class="car-thumb-variant">eHDi 90 Seduction E6G</div>
<div class="car-thumb-image" style="background-image: url('https://online.leasingcar.dk/Views/Public/GetPDFDocument.aspx?imageId=18442')"/>
<div class="car-thumb-details clearfix">
<div class="car-thumb-specs">1. ydelse 24.838 Kr. | 36 mdr. | 15.000 Km     | Inkl. service | Inkl. moms</div>
</div>

我想要的结果是："/privatleasing/Citro%c3%abn-Berlingo/eHDi-90-Seduction-E6G"

以下xpath似乎适用于Firepath并突出显示我想要的内容：

//div[@class='car-thumb-item clickable vehicle   ']/@data-nice_url

但是当我运行代码时，它每次都会超时？我的代码如下所示：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
import unittest


class DataTest(unittest.TestCase):
def setUp(self):
    self.driver = webdriver.Firefox()
    self.driver.get("http://www.leasingcar.dk/privatleasing")

def testData(self):
    driver = self.driver
    urlXpath = "//div[@class='car-thumb-item clickable vehicle   ']/@ data-nice_url"

    carLinks = WebDriverWait(driver, 30).until(lambda driver:  driver.find_elements_by_xpath(urlXpath))

    for car in carLinks:
        print car

def tearDown(self):
    self.driver.quit()


if __name__ == '__main__':
unittest.main()

提前致谢

Answer 1

您可以先通过XPath获取元素，然后使用AtomicInteger的方法WebElement来检索所需的信息。

示例：

get_attribute

Answer 2

urlXpath = //div[@class="car-thumb-item clickable vehicle"] 
nice_url = driver.find_element_by_xpath(urlXpath).get_attribute("data-nice_url")

Answer 3

我会依赖data-nice_url属性和vehicle类：

的存在

vehicle = driver.find_element_by_xpath('//div[@data-nice_url and contains(@class, "vehicle")]')
print(vehicle.get_attribute("data-nice_url")

WebDriverWait适用于您的代码：

wait = WebDriverWait(driver, 30)
car_links = wait.until(lambda driver: driver.find_elements_by_xpath('//div[@data-nice_url and contains(@class, "vehicle")]'))

for car in carLinks:
    print car

另外，还有一个CSS选择器：

vehicle = driver.find_element_by_css_selector('div.vehicle[data-nice_url]')
print(vehicle.get_attribute("data-nice_url")

Selenium xpath元素属性
