Demonstrates how to insert an XML tree or subtree into another XML document using the InsertChildTreeAfter method. PowerBuilder

// Build the 1st XML document:
// <x1>

//         <b2>22</b2>

    destroy loo_Xml
    destroy loo_Xml2

loo_Xml.InsertChildTreeAfter(li_Index,loo_Xml2)

Write-Debug loo_Xml.GetXml()

// The result is:

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

//     </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:
loo_Xml2.UpdateChildContent("b3","33333333")

Write-Debug loo_Xml.GetXml()

// The result:

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