Python Selenium webdriver帮助查找元素 我的目标是获得一个出现多次的特定元素的屏幕截图。 示例URL:，我想获取https://i.imgur.com/kcd98bQ.png 因此，我查看了代码，发现：`complemental results`，不幸的是`element=driver.find\u elements\u by_class\u name（“Uo8X3b”）`不起作用，因为`class=“Uo8X3b”`发生了几次： <h1 class="Uo8X3b">Accessibility links</h1> <h1 class="Uo8X3b">Search modes</h1> <h1 class="Uo8X3b">Search Results</h1>< <h2 class="Uo8X3b">Web results</h2> <h2 class="Uo8X3b">Notices about Filtered Results</h2> <h1 class="Uo8X3b">Page navigation</h1> <h2 class="Uo8X3b">Complementary results</h2> <h3 class="Uo8X3b">Images</h3> <h2 class="Uo8X3b">Description</h2> <h2 class="Uo8X3b">Description</h2> <h1 class="Uo8X3b">Footer links</h1>

结果:

[<selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="0c5b38af-7350-4d54-968e-2dbf1bcfd590")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="59f03910-6787-4009-9793-c9f2ad2fb42b")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="d124b2ca-ac51-401f-9e9c-653627af439c")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="35728814-738c-4f45-92cc-2c1353fdda0a")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="b1491e4c-7d69-4ca1-b0b5-a2cf56382041")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="70774d08-5e42-499e-9e81-8c7a61763a63")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="3e9ef6a4-9013-4421-810d-6a0a9f2357ce")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="289735b1-3685-4f9a-9156-f1af4a3d1ebf")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="b6a2eda1-8038-4dd1-9047-36cf263863c1")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="ebe87746-7bf3-495c-8660-3ca823c6e4b1")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="de8af129-a648-4862-a7de-c9486e7d16e2")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="ce4de9f5-337f-4151-8a0a-e289bc9d7d2a")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="456b2fbf-353b-4de9-b6ad-6377d13addbd")>, <selenium.webdriver.remote.webelement.WebElement (session="7bc20d0d87be84ee463612341bbd4d1e", element="3e877977-2e16-4639-a497-c4099f83a872")>]

使用xpath

 //h2[@class="Uo8X3b" and contains(text(),"Complementary"]

或

第二个将搜索精确文本第一个将搜索子字符串

#!/usr/bin/env python3
