XML AppendChild

hello world.

I am trying to append some child nodes? and remove "default".  I am getting thrown off by the long names of each node "<setting name = "Clients" serializeAs="xml">"

<?xml version="1.0" encoding="utf-8"?>

<configuration>   

    <userSettings>

        <RAAD.My.MySettings>            

            <setting name="Clients" serializeAs="Xml">

                <value>

                    <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                        xmlns:xsd="http://www.w3.org/2001/XMLSchema">

                        <string>default</string>

                    </ArrayOfString>

                </value>

            </setting>            

        </RAAD.My.MySettings>

    </userSettings>

</configuration>

$cfg_file = "C:\user.config"
 
$oXML = ObjCreate("Microsoft.XMLDOM")
 
If Not IsObj($oXML) Then
    MsgBox(0, "", "Unable to create COM session to XML.")
    Exit
EndIf
 
$stest = FileRead($cfg_file)
$oXML.LoadXML($stest)
 
ConsoleWrite($oXML.xML)
