How to iterate through XML in Powershell?

PowerShell has built-in XML and XPath functions.You can use the Select-Xml cmdlet with an XPath query to select nodes from XML object and then.Node.'#text' to access node value.

[xml]$xml = Get-Content $serviceStatePath$nodes = Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml$nodes | ForEach-Object {$_.Node.'#text'}

Or shorter

[xml]$xml = Get-Content $serviceStatePathSelect-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml |  % {$_.Node.'#text'}

You can also do it without the [xml] cast. (Although xpath is a world unto itself. https://www.w3schools.com/xml/xml_xpath.asp)

$xml = (select-xml -xpath / -path stack.xml).node$xml.objects.object.property

Or just this, xpath is case sensitive. Both have the same output:

$xml = (select-xml -xpath /Objects/Object/Property -path stack.xml).node$xmlName         Type                                                #text----         ----                                                -----DisplayName  System.String                                       SQL Server (MSSQLSERVER)ServiceState Microsoft.SqlServer.Management.Smo.Wmi.ServiceState RunningDisplayName  System.String                                       SQL Server Agent (MSSQLSERVER)ServiceState Microsoft.SqlServer.Management.Smo.Wmi.ServiceState Stopped
