Write XML Document To Group Information From Two Different Sub Routines

I am trying to retrieve all processes running on a machine with the usual information; process id, name and the memory usage. I am trying to export it all under one xml file, however to get all the information I had to use 2 separate methods. To get the process id, name and session id (process owner) I used the following code along with a dictionary and a class, using a .net library called Cassia.

Using server As ITerminalServer = manager.GetRemoteServer("Spartacus")
server.Open()
For Each process As ITerminalServicesProcess In server.GetProcesses()
If Not String.IsNullOrEmpty(process.ProcessId) Then
dictprocess.Add(process.ProcessId, New Processes(process.ProcessId, process.ProcessName, process.SessionId))
[Code] .....

As you can see the unique id (process id) is the same in each xml. Is there any way I can write the xml so that the information from both methods can be under one tag?
