Load an XmlNodeList into an XmlDocument without looping? | I originally asked this question on [RefactorMyCode](http://refactormycode.com/codes/36-load-xmlnodelist-into-an-xmldocument), but got no responses there... 


Basically I'm just try to load an `XmlNodeList` into an `XmlDocument` and I was wondering if there's a more efficient method than looping.



```
Private Function GetPreviousMonthsXml(ByVal months As Integer, ByVal startDate As Date, ByVal xDoc As XmlDocument, ByVal path As String, ByVal nodeName As String) As XmlDocument
    '' build xpath string with list of months to return
    Dim xp As New StringBuilder("//")
    xp.Append(nodeName)
    xp.Append("[")
    For i As Integer = 0 To (months - 1)
      '' get year and month portion of date for datestring
      xp.Append("starts-with(@Id, '")
      xp.Append(startDate.AddMonths(-i).ToString("yyyy-MM"))
      If i < (months - 1) Then
        xp.Append("') or ")
      Else
        xp.Append("')]")
      End If
    Next

    '' *** This is the block that needs to be refactored ***
    '' import nodelist into an xmldocument
    Dim xnl As XmlNodeList = xDoc.SelectNodes(xp.ToString())
    Dim returnXDoc As New XmlDocument(xDoc.NameTable)
    returnXDoc = xDoc.Clone()
    Dim nodeParents As XmlNodeList = returnXDoc.SelectNodes(path)
    For Each nodeParent As XmlNode In nodeParents
      For Each nodeToDelete As XmlNode In nodeParent.SelectNodes(nodeName)
        nodeParent.RemoveChild(nodeToDelete)
      Next
    Next

    For Each node As XmlNode In xnl
      Dim newNode As XmlNode = returnXDoc.ImportNode(node, True)
      returnXDoc.DocumentElement.SelectSingleNode("//" & node.ParentNode.Name & "[@Id='" & newNode.Attributes("Id").Value.Split("-")(0) & "']").AppendChild(newNode)
    Next

    '' *** end ***
    Return returnXDoc
End Function

```
