Adding a node to an existing XML file

[avolkman]

I've just begun learning XML and XPATH, so I'm currently at a very beginner level. I have an existing XML file that I would like to add an additional node to before saving it to another variable. The code looks like this:

Code:

'Create and load the XmlDocument
Dim doc As XmlDocument = New XmlDocument()
doc.LoadXml(lsum.XmlDoc.InnerXml)

'Create new node
Dim regionElement As XmlElement = doc.CreateElement("Region")
regionElement.InnerText = aryFolders(i).ToString.Trim()

'Add node to proper location
Dim node As XmlNode = doc.SelectSingleNode("/Collection/Content/Html/root")
node.AppendChild(regionElement)

'Insert new element into original XML file
xString &= doc.InnerXml.ToString



Now, I've managed to add the new node, but I can't seem to get it to go where I'd like it to within the XML structure. I'm sure it's something simple that I'm overlooking. Could someone please help me? Thanks!
