我的问题是，我需要包含网站 https://applipedia.paloaltonetworks.com 的子域的网格中的所有数据。 -(包含名称、类别、子类别、风险、技术的数据)。我需要的是[示例:第 5 行:2ch 有 2 个子域 |_2ch-base 和 2ch-posting。像这样我只想获取所有具有子域的应用程序的列表]
每当我尝试在行中添加任何内容时都不会:
table =wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, 'tbody#bodyScrollingTable tr')))
我收到超时错误。
下面是我现在拥有的脚本，它从网格中获取所有数据，但我只需要应用程序，并且它包含子域。[示例 2ch、2ch-base、2ch-posting]。我通过检查元素发现了一种模式，即所有没有子域的应用程序都具有 ( )，或者我们可以通过 () 字段，该字段对于所有具有子域的应用程序都很常见。任何有关解决此问题的帮助将不胜感激。
