Selenium-如何在下面的场景中单击图像

存在一个带有网格的表，我想通过名称选择一个网格，并仅删除其icd9代码。请注意，所有网格都有相同的icd9代码，因此我不能使用span id。下面是代码。请让我知道如何映射icd9代码span id=“700>482834823以下是可用于标识链接的xpath：

---

//*[@id=“containerChloride”]//a

你好，山姆，我已经有了这个，但我的疑问是，如果你看到上面的代码，在下一个td中会有一个span id。我需要使用这个容器氯化物作为参考来点击它。如何做？如何使用@id=“containerChloride”链接2个td“作为参考，我认为你想要链接。如果您想要span，那么它仍然很容易：//*[@id=“containerChloride”]///span[@id=“700>48283
