Editing an XML document in C#
Question
I'm new to C#. I am attempting to edit a spreadsheetXML 2003 document by adding a bunch of nodes to the different worksheets in it. Here is an example of the structure:
<Workbook>
<Worksheet ss:Name="Contact">
<Table>
<Column />
<Row />
</Table>
</Worksheet>
<Worksheet ss:Name="Facility">
<Table>
<Column />
<Row />
</Table>
</Worksheet>
</Workbook>
What I need to do is to load this XML and insert new nodes at certain places. I'm pretty sure I know how to create new XElement with the nodes under it that I need (there's plenty of tutorials online for that). What I'm having trouble finding is how to find a node and add nodes under it. This is as far as I've got:
XElement xmlDoc = XElement.Load(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\\Autodesk\\Revit\\Addins\\2013\\COBiev2.4Template.xml");
So, how do I find the "Facility" worksheet and add a new row under the table node in it? I need to be able to do this in such a way that at the end of my routine I can save the xmlDoc file back out to the file system.
---- UPDATE ----- I'm not getting this to work. Revised code and beginning of actual XML below.

var workbook = xmlDoc.Root.Element("Workbook");
if (workbook != null)

var element = (from e in workbook.Elements("Worksheet")
where e.Attribute("ss:Name").Value == "Facility"
select e).FirstOrDefault();
if (element != null)

TaskDialog.Show("Worksheet", "Found Facility");
var tableNode = element.Element("Table");
if (tableNode != null)
{
TaskDialog.Show("Table", "Found Table");
tableNode.Add(new XElement("Row",
new XElement("Cell",
new XElement("Data", rDoc.ProjectInformation.Name)

));
}
}
}
else
{
TaskDialog.Show("Workbook", "Workbook not found");
}
The "Workbook" isn't being found. What am I not understanding about this, because this seems like it should work.

How about find a node like node = xmlDoc. Element
And check it's attribute by node. Attributes
Then, add nodes like node. Add

XElement is pretty easy to use, google it, you will find some useful tutorial
var element = (from e in xmlDoc.Elements("Worksheet")
where e.Attribute("Name").Value == "Facility"
select e).FirstOrDefault();
if (element != null)
{
var tableNode = element.Element("Table");
if (tableNode != null)
tableNode.Add(new XElement("Row"));
}
