Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

' Build the 1st XML document:
' <x1>
'     <a1>1</a1>
'     <a2>2</a2>
'     <a3>3</a3>
' </x1>

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Xml")
set xml = CreateObject("Chilkat.Xml")
xml.Tag = "x1"
xml.UpdateChildContent "a1","1"
xml.UpdateChildContent "a2","2"
xml.UpdateChildContent "a3","3"

' Build a 2nd XML document:

' <x2>
'   <b1>11</b1>
'   <b2>22</b2>
'   <b3>33</b3>
' </x2>

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Xml")
set xml2 = CreateObject("Chilkat.Xml")
xml2.Tag = "x2"
xml2.UpdateChildContent "b1","11"
xml2.UpdateChildContent "b2","22"
xml2.UpdateChildContent "b3","33"

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

' <x1>
'     <a1>1</a1>
'     <x2>
'         <b1>11</b1>
'         <b2>22</b2>
'         <b3>33</b3>
'     </x2>
'     <a2>2</a2>
'     <a3>3</a3>
' </x1>

' Insert xml2 after "a1"

index = xml.TagIndex("a1")
If (index < 0) Then
    outFile.WriteLine("a1 not found.")
    WScript.Quit
End If

xml.InsertChildTreeAfter index,xml2

outFile.WriteLine(xml.GetXml())

' The result is:

' <x1>
'     <a1>1</a1>
'     <x2>
'         <b1>11</b1>
'         <b2>22</b2>
'         <b3>33</b3>
'     </x2>
'     <a2>2</a2>
'     <a3>3</a3>
' </x1>

' 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"

outFile.WriteLine(xml.GetXml())

' The result:

' <x1>
'     <a1>1</a1>
'     <x2>
'         <b1>11</b1>
'         <b2>22</b2>
'         <b3>33333333</b3>
'     </x2>
'     <a2>2</a2>
'     <a3>3</a3>
