How to insert a value inside an XML tag in XML file using a PowerShell script?

Question

I have the following XML:

 <?xml version="1.0" encoding="utf-8"?>
 <Topology>
 <MyProjectserver1 desc="name of the server"></MyProjectserver1>
 </Topology>

I have tried the following, but it did not get update

$path = 'C:\newfolder\data.xml'
$MyProjectserver1 ='XYZAB'
$xml =[xml](Get-Content -Path $path)
$node =$xml.Topology.MyProjectserver1 |
Where {$_.desc -eq 'name of the server'}
$node =$MyProjectserver1
$xml.Save($path)

Once the above PowerShell script is executed, it did not update the XML content.

Ideally, the PowerShell script should update the server name in XML content as below:

 <?xml version="1.0" encoding="utf-8"?>
 <Topology>
 <MyProjectserver1 desc="name of the server">XYZAB</MyProjectserver1>
 </Topology>

Looking at your example, you need to set InnerText property of the XML node:

$node.InnerText = $MyProjectserver1

See XmlNode.InnerText documentation
