How to modify null value/two double quotes that contain nothing in xml with Powershell?
I need to modify web.config file which I am reading as xml and the line i need to change is this:
<add key="My.Unique.Repository" value="" /> as you can see, there is nothing in value=" " just the double quotes.
I have no script written for this, I am trying to find out how to do it in the simplest way before I attempt to compile code
P.S. I have zero powershell experience, kindly respond in simple terms, thank you
Probably something along the lines of
$xml = [xml]'<add key="My.Unique.Repository" value="" />' $target = $xml.SelectSingleNode("/add") $target.SetAttribute("value", "some value"); 
Found the answer that I needed, see the code below. Thanks Theo for providing me with this answer. https://stackoverflow.com/users/9898643/theo
$path = '\\lonngp-ap\c$\Program Files\AIR\IIS\web2.config' [xml]$config = Get-Content -Path $path -Raw $stuffIwant = "\\StringServer123" $config.SelectNodes("//add[@key='My.Unique.Repository']") | ForEach-Object { $_.SetAttribute("value", $stuffIwant) } $config.Save($path)
