Help with XML Creating/Modifying and Deleting Nodes

[Subz]

Can anyone assist with creating/modify/delete XML Nodes/Child Nodes?

Have a document for example:

<ConfigData>
    <parameter>
        <name>Setting One</name>
        <value>10</value>
    </parameter>
    <parameter>
        <name>IPAddress</name>
        <value>192.168.1.1</value>
    </parameter>
    <parameter>
        <name>Setting One</name>
        <value>200</value>
    </parameter>
    <parameter>
        <name>Setting Three</name>
        <value>300</value>
    </parameter>
</ConfigData>

Would like to add another node parameter/name, parameter/value, but unsure how to, when there are multiple instances with the same tagname for example, would like to add the following if the nodes do not already exist:

<parameter>
    <name>UserPreferredLanguage</name>
    <value>English</value>
</parameter>

Currently using the following to check and delete/modify existing nodes, was thinking of placing the name and value into a 2d array and then using a true/false in a 3rd column to return if the setting was found and modified or not, so I can decide whether I need to create the nodes or not, but I'm hoping there is a simpler way.\

Any assistance would be much appreciated.

PS: Have also written this with the XML Dom Wrapper UDF but still unsure how to proceed with checking nodes and creating them if they're missing, also couldn't find a function to delete a full node + parent using selectNodes, hence the custom __XML_DeleteNode function.

Thanks

Local $sXMLDocPath = @ScriptDir & "\XMLDoc.xml"
Local $oXMLDoc = ObjCreate("MSXML2.DOMDocument")
    $oXMLDoc.validateOnParse = False
    $oXMLDoc.load($sXMLDocPath)
Local $oXMLNodes = $oXMLDoc.selectNodes("ConfigData/parameter")
If IsObj($oXMLNodes) Then
    For $oXMLNode In $oXMLNodes
        If $oXMLNode.childNodes.item(0).tagName  = "Name" And $oXMLNode.childNodes.item(0).Text = "Setting One" Then
            If $oXMLNode.childNodes.item(1).tagName = "Value" Then $oXMLNode.childNodes.item(1).Text = 10
        EndIf
        If $oXMLNode.childNodes.item(0).tagName  = "Name" And $oXMLNode.childNodes.item(0).Text = "IPAddress" Then
            __XML_DeleteNode($oXMLNode)
        EndIf
        If $oXMLNode.childNodes.item(0).tagName  = "Name" And $oXMLNode.childNodes.item(0).Text = "Setting Two" Then
            If $oXMLNode.childNodes.item(1).tagName = "Value" Then $oXMLNode.childNodes.item(1).Text = 20
        EndIf
        If $oXMLNode.childNodes.item(0).tagName  = "Name" And $oXMLNode.childNodes.item(0).Text = "Setting Three" Then
            If $oXMLNode.childNodes.item(1).tagName = "Value" Then $oXMLNode.childNodes.item(1).Text = 30
        EndIf
    Next
EndIf

$oXMLDoc.Save ($sXMLDocPath)

Func __XML_DeleteNode($_oNode_Enum)
    If $_oNode_Enum.hasChildNodes Then
        For $_oNode_Enum_Child In $_oNode_Enum.childNodes
            If $_oNode_Enum_Child.nodeType = $XML_NODE_TEXT Then
                If StringStripWS($_oNode_Enum_Child.text, $STR_STRIPLEADING + $STR_STRIPTRAILING + $STR_STRIPSPACES) = "" Then
                    $_oNode_Enum.removeChild($_oNode_Enum_Child)
                EndIf
            EndIf
        Next
    EndIf
    $_oNode_Enum.parentNode.removeChild($_oNode_Enum)
EndFunc

Have you looked at XML.au3 UDF?

[Subz]

Thanks Danp2, yes have the latest XML.au3 and have used it with other projects, however in those situations I had an id attribute to identify each node, however in this current project they have no identifiers except for the innerText of the "name" tag, but not sure how I get the "value" tag or create a new parameter/name and parameter/version nodes.  Hope that made sense.

Do you still need help with this , or you already solve it ?

@mLipok After reading a lot of msdn and snippets I have got it working although, not sure if its the best way.

This is part of project to automate Avaya (VOIP) Client settings for each user that logs on.  First I created an Array with all audio devices, the id, guid and name.  Then to create the parameter node and sub-nodes I used the following.  I know you're a guru on xml, do you think below is the best approach?  Or is there an easier way?  Always happy to learn something new.

 I'm not sure you are realy thought about me ...

btw. after a quick review, I think your aproach is good as far this is working, as so far I can only sugest to you to try this clonNode method:
