Help using VB Script to edit an XML File

So work gave me a project. I'm a novice programmer at best (just enough to pass the two Java Programming courses required by my degree), and I'm more of a hardware and troubleshooting guy. So I'm here asking for some assistance.. bacon needs saving here... I'm trying to edit this XML File, specifically the tags /accounts/a0/name and /accounts/a0/jid.

Code:

---

<!DOCTYPE accounts>
<accounts version="0.14" xmlns="http://psi-im.org/options">
    <accounts>
        <a0>
            <tls>
                <override-certificate type="QByteArray">
                </override-certificate>
                <override-domain type="QString">
                </override-domain>
            </tls>
            <custom-auth>
                <use type="bool">false</use>
                <authid type="QString">
                </authid>
                <realm type="QString">
                </realm>
            </custom-auth>
            <log type="bool">true</log>
            <use-host type="bool">false</use-host>
            <stun-port type="QString">3478</stun-port>
            <security-level type="int">0</security-level>
            <port type="int">5222</port>
            <ignore-SSL-warnings type="bool">false</ignore-SSL-warnings>
            <keep-alive type="bool">true</keep-alive>
            <connect-after-sleep type="bool">true</connect-after-sleep>
            <pgp-secret-key-id type="QString">
            </pgp-secret-key-id>
            <name type="QString">Default</name>
            <ssl type="QString">auto</ssl>
            <reconn type="bool">true</reconn>
            <proxy-id type="QString">
            </proxy-id>
            <bytestreams-proxy type="QString">
            </bytestreams-proxy>
            <priority type="int">5</priority>
            <jid type="QString">[email protected]</jid>
            <resource type="QString">Psi</resource>
            <password type="QString">
            </password>
            <compress type="bool">false</compress>
            <automatic-resource type="bool">true</automatic-resource>
            <legacy-ssl-probe type="bool">true</legacy-ssl-probe>
            <require-mutual-auth type="bool">false</require-mutual-auth>
            <enabled type="bool">true</enabled>
            <auto type="bool">true</auto>
            <allow-plain type="QString">over encryped</allow-plain>
            <stun-host type="QString">
            </stun-host>
            <host type="QString">
            </host>
        </a0>
    </accounts>
</accounts>

I need to edit the text of /accounts/a0/name to be the username currently logged onto the windows machine, and the text of /accounts/a0/jid to read <username>@abc.123.com. I need the script to make these changes, then reach out and start an executable in the program files. This is what I have so far.

Code:

---

Dim strPsiUser

Set oWshShell = WScript.CreateObject ("WScript.Shell")
strPsiUser = oWshShell.ExpandEnvironmentStrings ("%UserName%")

Set xmlDoc = _
  CreateObject("Microsoft.XMLDOM")
xmlDoc.Async = "False"
xmlDoc.Load("C:\My Documents\accounts.xml")

xmlDoc.Save "C:\My Documents\accounts.xml"

I've not had luck with code to set the text, and everything I have tried to save the file ends up with a blank file. I would appriciate any assistance you could offer.

Thank You!

This should handle the xml part.

One thing I see with your xml is the doctype node is incomplete and will cause the load of your file to fail. Either remove the node or make sure it is complete.
<!DOCTYPE accounts>

Code:

---

Option Explicit
Dim xmlDoc, objNode
Dim strFile
Dim strUserName, strID


    strUserName = "MyUserName"
    strID = strUserName & "@abc.123.com"

    ' Path to your xml file
    strFile = "C:\My Documents\accounts.xml"
   
    ' Create an xml Documment object and load your file
    Set xmlDoc =  CreateObject("Microsoft.XMLDOM")
    xmlDoc.Async = "False"
    xmlDoc.Load  strFile

    ' Find the accounts/a0/name node
    Set objNode = xmlDoc.SelectSingleNode("accounts/accounts/a0/name")
    ' Test that a node was returned
    If Not objNode Is Nothing Then
        objNode.Text = strUserName
    End If
   
    ' Find the accounts/a0/jid node
    Set objNode = xmlDoc.SelectSingleNode("accounts/accounts/a0/jid")
    ' Test that a node was returned
    If Not objNode Is Nothing Then
        objNode.Text = strID
    End If

    ' Save the changes
    xmlDoc.Save strFile
   
    ' Clean up
    If Not objNode Is Nothing Then
        Set objNode = Nothing
    End If
   
    Set xmlDoc = Nothing

Thank you for the response.

I was not aware that the XML document declaration was incomplete. It is generated by the program, so I'm not sure if it's possible to change it. I'll experiment with it and thank for this code! Bacon is saved, if only I could send you a BLT now! :D
