我是 C# 的新手。我正在尝试通过将一堆节点添加到其中的不同工作表来编辑电子表格 XML 2003 文档。下面是一个结构示例：
<Workbook>
<Worksheet ss:Name="Contact">
<Table>
<Column />
<Row />
</Table>
</Worksheet>
<Worksheet ss:Name="Facility">
<Table>
<Column />
<Row />
</Table>
</Worksheet>
</Workbook>
我需要做的是加载这个 XML 并在某些地方插入新节点。我很确定我知道如何使用我需要的节点创建新的 XElement（网上有很多教程）。我很难找到的是如何找到一个节点并在它下面添加节点。这是据我所知：
XElement xmlDoc = XElement.Load(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\\Autodesk\\Revit\\Addins\\2013\\COBiev2.4Template.xml");
那么，如何找到“设施”工作表并在其中的表节点下添加新行？我需要能够以这样一种方式做到这一点，即在我的例程结束时，我可以将 xmlDoc 文件保存回文件系统。
---- 更新 ----- 我没有让这个工作。修改后的代码和实际 XML 的开头如下。

找不到“工作簿”。我对此有什么不理解，因为这似乎应该有效。
