How to change the value of XML Element attribute using PowerShell?

Question

I am trying to access and change the particular attribute from XML tag

XML:

<office>   <staff branch="Hanover" Type="sales">     <employee>         <Name>Tobias Weltner</Name>         <function>management</function>         <age>39</age>     </employee>     <employee>         <Name>Cofi Heidecke</Name>         <function>security</function>         <age>4</age>     </employee>   </staff>   <staff branch="London" Type="Technology">    <employee>     <Name>XXXX</Name>     <function>gement</function>     <age>39</age> 

From the above example I want to print branch attribute and then want to change it with one value such as New York in all the whole XML and using below code to do that

       $xml=New-Object XML        $xml.Load("C:\FE6Work.xml")        $node=$xml.SelectNodes("/office/staff")        write-output $node.branch       $node.branch="New York" 

But get an error stating can't find the element.

Can someone please help?

Try the following:

$nodes = $xml.SelectNodes("/office/staff"); foreach($node in $nodes) {     $node.SetAttribute("branch", "New York"); } 

This will iterate through all nodes returned by SelectNodes() and modify each one.
