' Build the 1st XML document:
' <x1>
'     <a1>1</a1>
'     <a2>2</a2>

set xml = Server.CreateObject("Chilkat.Xml")

' We want to insert xml2 into xml to get this:

'     <x2>
'         <b1>11</b1>
'         <b2>22</b2>

' Insert xml2 after "a1"

If (index < 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( "a1 not found.") & "</pre>"
    Response.End
End If

xml.InsertChildTreeAfter index,xml2

Response.Write "<pre>" & Server.HTMLEncode( xml.GetXml()) & "</pre>"

' The result is:

' <x1>
'     <a1>1</a1>
'     <x2>
'         <b1>11</b1>
'         <b2>22</b2>

' Note: xml2 now points to the subtree within xml.
' For example, update "b3" and then see how it's updated within the merged document:
xml2.UpdateChildContent "b3","33333333"

Response.Write "<pre>" & Server.HTMLEncode( xml.GetXml()) & "</pre>"

' The result:

' <x1>
'     <a1>1</a1>
'     <x2>
'         <b1>11</b1>
'         <b2>22</b2>
'         <b3>33333333</b3>
'     </x2>
