Paul,
If you always want all the child nodes of the selected menu element,
it is pretty straightforward. The one thing you need to do that is
not obvious is using import node. Also it looks like your current
code for building the second XML document is working on the original
xmlDoc. Also remember xpath is case-sensitive. What I'd do...
'create new doc and its root nood
Dim xmlSubMenu As XmlDocument = New XmlDocument
Dim rootNode As XmlElement = xmlSubMenu.CreateElement("menu")
xmlSubMenu.AppendChild(rootNode)
Dim strMenuItemText As String = "Settlement" '-- Hardcoded here
Dim myXPath As String =
String.Format("/menu/menuItem[text='{0}']/subMenu", strMenuItemText)
'this should point to subMenu node for Settlement menuitem if the
Xpath is right
xmlNode = menuXML.SelectSingleNode(myXPath)
'get child nodes and add them into the the new doc.
dim nChild as XmlNode
Dim nChildForNew as XmlNode
for each nChild in xmlNode.ChildNodes
nChildForNew = xmlSubMenu.ImportNode(nChild, true)
rootNode.AppendChild(nChildForNew)
next
that should be all there is to it.
