I have the following xml:

And I need to alter the item key WorkDir in Powershell. When using “regular” xml-read I get to the top sections (options, users, and so on) but not the “item key” nodes within each. How can I edit the value for WorkDir in powershell? (I realize I could just use a dirty string replace but I’d rather do it “properly”.

    This version uses a bit more PowerShell and handles the case of mulitple items with WorkDir keys:

    $xml = [xml](Get-Content foo.xml)
$xpath = "/sections/section/item[@key='WorkDir']" 
Microsoft.PowerShell.Utility\Select-Xml $xml -XPath $xpath |
    Foreach {$_.Node.SetAttribute('value', $pwd)}
$xml.Save("$pwd\bar.xml")

    Note, if you have the PowerShell Community Extensions installed you can use the Format-Xml cmdlet to format the output and save it via Out-File e.g.:

    $xml | Format-Xml -AttributesOnNewLine | Out-File bar.xml -enc utf8

    OTOH $xml.Save() is easier except that you must remember that it probably doesn’t have the correct current dir if you were to specify just the filename. That’s why I used “$pwd\bar.xml” in the first example. This is not an issue with PowerShell cmdlets like Out-File.
