Error in Appending XML Element

[Shaurya Vardhan]

Hi,
On Appending a child in XML Node,
I am having error, "Run-time exception thrown : System.ArgumentException -
The node to be inserted is from a different document context."

How to resolve this ?
I am attaching image of error message.

Thanx & Regards,
Shaurya Vardhan

Hi Shaurya,

Maybe if you send some code someone can help you.
(Only the part of the error and then first pasted in a notebook copied and
than in the mail, otherwise it is mostly unreadable)

each xmlDocument has its own 'context'. you cannot add a node from
xmlDoc1 to xmlDoc2.

I needed it for small documents, so I created a xmlDoc3 and added to it
the nodes I needed from xmlDoc1 and xmlDoc2:

' --------------------------------------------
Public Shared Function mcXNodeListsAppend(ByVal xL1 As
XmlNodeList, ByVal xL2 As XmlNodeList) As System.Xml.XmlNodeList
' -----------------------------------------------
' Description: Append two XmlNodeLists into one list.
' I cannot simply append nodes, because of exception - "The node
to be inserted
' is from a different document context", So, I create a 3rd
list, and import
' each node from both original nodeLists to the 3rd one.
' ----------------------------------------------

'-- Create a new xmlDocument with one root node.
Dim tempDoc As New XmlDocument()
tempDoc.LoadXml(("<xxRoot></xxRoot>"))

Dim tempNode As XmlNode
Dim tempFragment As XmlDocumentFragment =
tempDoc.CreateDocumentFragment()

Dim maxI As Integer
Dim i As Integer

'-- Add childs to the root from both lists.
'-- Get xL1 elements:
If Not (xL1 Is Nothing) Then
maxI = xL1.Count
If (maxI > 0) Then
For i = 1 To maxI
tempNode = tempDoc.ImportNode(xL1.Item(i - 1), True)
tempDoc.DocumentElement.AppendChild(tempNode)
Next i
End If
End If

'-- Get xL2 elements:
If Not (xL2 Is Nothing) Then
maxI = xL2.Count
If (maxI > 0) Then
For i = 1 To maxI
tempNode = tempDoc.ImportNode(xL2.Item(i - 1), True)
tempDoc.DocumentElement.AppendChild(tempNode)
Next i
End If
End If

'-- Return the root ChildNodes.
Return tempDoc.FirstChild.ChildNodes

End Function
