Replace XML Attributes using PowerShell

Question

Currently want to replace the from, to and subject attributes of an XML file using a PowerShell script.

<configuration>
<configSections>
</configSections>
<elmah>
 <errorLog type="Elmah.SqlErrorLog, Elmah" connectionStringName="SqlServer" />
    <errorMail from="[email protected]" to="[email protected]" cc="" subject="Error email title"/>
    <errorFilter>
    <test>
     </test>
 </errorFilter>
</elmah>

I have tried the following foreach loop but this doesnt seem update the attributes:

$xmlDoc = [XML](Get-Content "$path\Web.config")
foreach ($item in  $xmlDoc.configuration.elmah.errorMail){
{$item.from = '[email protected]'}
{$item.to = '[email protected]'}
{$item.subject = 'test3'}
}
$xmlDoc.Save("$path\Web.config")

Anyone help with this script?

You are wrapping the assignment in a scriptblock which will probably introduce new variables and prevent the properties in the xml from beeing updated. So just remove the curly brackets:

$xmlDoc = [XML](Get-Content "$path\Web.config")
foreach ($item in  $xmlDoc.configuration.elmah.errorMail)
{
    $item.from = '[email protected]'
    $item.to = '[email protected]'
    $item.subject = 'test3'
}
$xmlDoc.Save("$path\Web.config")
