我正在从事一个web自动化项目。这个项目是我个人的，因为我必须不断点击并填写网络应用程序(IBM Maximo Asset Management(上的文本字段。登录，然后单击我想去的链接最初工作得很好，但当我开始单击每一新行上的文本字段时，我会出现错误。就好像添加一个新行会改变整个DOM，但它只会在DOM中创建另一个表，而其他表则保持不变。如果可能的话，我很想有一个合作者帮我解决这个问题。
你会看到，在一些地方，由于自动化刚刚中断，我不得不使用完整的XPATH，例如：
if driver.find_element(
By.XPATH,
"/html/body/form/div/table[2]/tbody/tr/td/table/tbody/tr/td/table/tbody/tr/td/table/tbody/tr[2]/td/div/table/tbody/tr/td/div/table/tbody/tr/td/table/tbody/tr/td/div/table/tbody/tr/td/table/tbody/tr[2]/td/table/tbody/tr[2]/td/div/table/tbody/tr[3]/td/table/tbody/tr[3]/td/table/tbody/tr[4]/td[10]").text == "WSCH":
如果没有完整的XPATH，代码就找不到这个元素。那么，我应该为所有元素使用完整的XPATH进行编码吗？请提出建议。
我觉得我应该为整个代码做这件事，但如果网络应用程序被更改或更新，这将使更改变得非常困难。
这是我的全部代码。

StaleElementException: element is not attached to page
意味着元素的先前引用现在已经过时，并且元素引用不再存在于页面的HTML DOM的当前状态中。
此异常背后的常见原因可能是以下任一原因：
- 元素已经改变了它在HTML DOM中的位置
- 元素不再附加到DOM树
- 元素所在的网页已刷新
- 元素的上一个实例已由JavaScript刷新
此用例
您的怀疑"when I start clicking on text fields on each new row that I get errors. It's as if adding a new row changes the whole DOM"是绝对正确的，因为"creates another table in the DOM"肯定会更改DOM树中先前标识的元素的位置，尽管其他元素保持不变。
