Compare part of node xml files using powershell

I want to compare a part of the xml-tree of two files (GPO->Computer from a GPOReport).

$Xml1 = Get-Object $Path1
$Xml2 = Get-Object $Path2

Compare-Object ($Xml1) -DifferenceObject ($Xml2)

gives the complete differences from the file. But I want only part of the node.

Comparing trees (ie. an XML document) is a bit more complicated than comparing two lists (like the lines in two files).

It's unclear from your question how extensive a comparison you're looking for here, but if you're only interested in testing a single value or attribute between two XML documents, the easiest is probably with Select-Xml:

$xml1 = [xml]@'
<root>
  <nodegroup>
    <node name="myNode">SomeValue</node>
  </nodegroup>
</root>
'@
$xml2 = [xml]@'
<root>
  <nodegroup>
    <node name="myNode">SomeOtherValue</node>
  </nodegroup>
</root>
'@

$res1,$res2 = $xml1,$xml2 |Select-Xml -XPath 'root/nodegroup/node[@name = "myNode"]'

if($res1.Node.InnerText -eq $res2.Node.InnerText){
    # the inner text value of the selected node is the same in both documents
}
