How to update string in attribute [xml] using powershell?

I have many web.config files. The URL contains the name of the machine.

This is my example web.config file

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.Model>
<client>
      <endpoint address="http://MyMachineName:80/MyProj/Core/NewService/SecurityObject.0/Secretservice.svc" binding="basicHttpBinding" bindingConfiguration="MyProj_Internal_Routing" behaviorConfiguration="UserSIDBehavior" contract="SecurityMgmt.SecurityMgmtContract" name="HttpEndpointSecMgt" />
      <endpoint address="http://MyMachineName:80/MyProj/Core/DataObject/SystemCatalogs1.0/DataObjectservice/DataObjectservice.svc" binding="basicHttpBinding" bindingConfiguration="MyProj_Internal_Routing" behaviorConfiguration="UserSIDBehavior" contract="DataObjectservice.SystemCatalogsDataObjectservice" name="BasicHttpBinding_SystemCatalogsDataObjectservice" />
      <endpoint address="http://MyMachineName:80/MyProj/Core/NewService/Movement.0/Movement.svc" binding="basicHttpBinding" bindingConfiguration="MyProj_Internal_Routing" behaviorConfiguration="UserSIDBehavior" contract="NavigationClientLib.NavigationNewService" name="BasicHttpBinding_NavigationNewService" />
 </client>

 <system.Model>

 </configuration>

When the user changes the name of the machine, this should be updated in all xml files.

I decided to write such a function.

    Function Update-MachineName ([string] $FilePath,[string] $xpath, [string] $NewMachineName="NewComputer") {


    # Get the config file contents
    $WebConfig = [XML] (Get-content $Filepath)

    #Find the url using xpath which has old Machine name 
    $hostnameString= Select-XML -XML $WebConfig -XPath $Xpath

    Foreach ( $hostname in $hostnameString) { 

           if ( ($hostname.Node.value -match 'http') -eq $true ) {

               $hostname.Node.value
               $MachineOldName = $($($hostname.Node.value.split("/"))[2].split(":"))[0]
               $MachineOldName

               $hostname.Node.value.replace( $MachineOldName,$NewMachineName)

           }
    }

 $WebConfig.Save($FilePath)
}

Update-MachineName "C:\web.config" "//@address"

Although I am replacing the new machine name, the contents of web.config are not updated. How to update it with the new name Machine

Your replacement value is not stored on node. Change this line:

$hostname.Node.value.replace( $MachineOldName,$NewMachineName)

For

$hostname.Node.value=$hostname.Node.value.replace( $MachineOldName,$NewMachineName)

If this is just to replace the machine names in the XML structure that you talked about above, you don't need to parse the XML and use XPath ...

$oldMachineName = "MyMachineName"
$newMachineName = "MyBrandNewMachineNAme"

$content = Get-Content -path $filePath
$content | foreach { $_.Replace($oldMachineName, $newMachineName) } | Set-Content $filePath

:

$nodoEndpointSvcAddress = $($configXml.configuration.'system.serviceModel'.client.endpoint |  where { $_.name -eq "MyEndPoint1" })
[string]$endpointSvcAddress = $nodoEndpointSvcAddress.address
Write-Host $endpointSvcAddress

# Replace
$server = "test"
iif ($endpointSvcAddress.Contains($server))
{
    Write-Host "`r`nReplace $endpointSvcAddress"
    $nodoEndpointSvcAddress.address=$nodoEndpointSvcAddress.address.replace( $server,"PROSERVER")
    Write-Host ("Replaced " + $nodoEndpointSvcAddress.address)

}

$configXml.Save($pathCDR)
