无法使用硒定位元素

Question

我已经审查了与该热门主题相关的几个问题，但尚未找到解决方案。我正在尝试抓取一个动态网页，该网页要求用户单击某些内容然后输入一些输入。我要抓取的网站在这里：https://a810-dobnow.nyc.gov/publish/#!/

我试图单击显示“建筑物标识号”的位置，然后继续输入一些内容。我似乎甚至找不到我需要单击的元素。我使用了等待，还检查了它是否位于我需要切换到的其他帧中，据我所知，它不远：

driver = webdriver.Chrome("C:\\Users\\#####\\Downloads\\chromedriver_win32\\chromedriver.exe")
driver.get("https://a810-dobnow.nyc.gov/publish/#!/")
element = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, "//*[@id=""accordiongroup-9-9180-tab""]/h4/a/span/h3")))
driver.find_element_by_xpath("//*[@id=""accordiongroup-9-9180-tab""]/h4/a/span/h3").click()

Answer 1

我刚刚加载了页面，当我尝试在dom中搜索您提供的xpath时，找不到匹配的元素。 我建议使用类似的东西：
