Question

您好，我想使用硒<li>www.fastreact.co.uk</li>导航到此确切的供应商URL。但是我被困在这一部分。

vendor_url = browser.find_element_by_xpath('//ul[@class="check-list"]')
#vendor_url = browser.find_element_by_xpath('//ul[@class="check-list"][3]')

如何导航到确切的UL？从源代码中可以看到，UL包含class="check-list ... "的情况有四次。
同样，一旦我设法导航到该节点，如何将硒Web元素输出到人工文本中？

<h2 class="epsilon"><i class="ss-buildings  icon-lead  zeta"></i>VendorDetails</h2>
<ul class="check-list" >
    <li>Fast React Systems</li>
    <li>www.fastreact.co.uk</li>
    <li>Founded 1999</li>
    <li>United Kingdom</li>
</ul>

Answer 1

这是您想要的工作示例：

注意：这已在带有chromedriver 2.40的Chrome build 67上进行了测试

driver.get('https://www.capterra.com/p/14890/Fastreact/')

# this will go directly to the check-list item you are wanting
vendor_details = driver.find_element_by_xpath('.//ul[@class="check-list"][2]')
print(vendor_details.text)

# this will go directly to the link you are wanting
vendor_link= driver.find_element_by_xpath('.//ul[@class="check-list"][2]/li[2]')
print(vendor_link.text)

print 语句将显示控制台中元素的文本值。

根据您要提取供应商URL 的问题，您需要诱使 WebDriverWait 使所需的元素可见，您可以使用以下解决方案：

代码块：

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

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_argument('disable-infobars')
driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get("https://www.capterra.com/p/14890/Fastreact/")
print(WebDriverWait(driver, 20).until(expected_conditions.visibility_of_element_located((By.XPATH, "//h2[@class='epsilon' and contains(.,'Vendor Details')]//following::ul[1]//following-sibling::li[2]"))).get_attribute("innerHTML"))

控制台输出：
```
www.fastreact.co.uk
```

如何构造XPath以从父ul标签提取URL www.fastreact.co.uk？
