PowerShell replace text between two string

Question

I am trying to modify config.xml.
config.xml content is

<command>
some lines here 2
</command>
some lines here 3

So I want to replace the content between <command> and </command>. Here is what I tried doing

$Replace = Get-Content D:\Temp\Replace.txt
$ReplaceWith = Get-Content D:\Temp\ReplaceWith.txt

$regex = '(<command>\d*).*?(</command>\d*)'
$Replace -replace $regex, $ReplaceWith

But its not working. Need help.

Use -Raw with Get-Content and also add (?s) at the regex start. Also, if your replaceWith.txt contains plain text (not a specifically formatted regex replacement string) and if you have $ in the replacement, you need to double them and remove \d* and parentheses. — Wiktor Stribiżew

so will the regex look like this $regex = '(?s)(<command>\d*).*?(</command>)(?s)' — vikram athare

don't parse xml with regex. Instead, read as xml and either dot index ($myconfig.topnode.othernode.command) or SelectNode — G42

Thanks gms0ulman. I was able to do this using reading as xml in powershell, below was the code

$ReplaceWith = Get-Content C:\psscript.ps1 -Raw
[xml]$ConfigXml = Get-Content "c:\config.xml" -Raw
$SelectCommandNode = $ConfigXml.SelectSingleNode("//command")
$SelectCommandNode.InnerText = $ReplaceWith
$ConfigXml.Save("c:\config.xmll")
