python - Selenium xpath 元素属性

Question

我正在尝试从“data-nice-url”元素获取属性，我的 html 如下所示:

<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 似乎在 Firepath 中有效并突出显示了我想要的内容:

//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

我会依赖于 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")

将 WebDriverWait 应用于您的代码:

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

作为替代方案，CSS 选择器:

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