$xmlsettings = New-Object System.Xml.XmlWriterSettings
$xmlsettings.Indent = $true
$xmlsettings.IndentChars = "    "

# Set the File Name Create The Document
$XmlWriter = [System.XML.XmlWriter]::Create("C:\YourXML.xml", $xmlsettings)

# Write the XML Decleration and set the XSL
$xmlWriter.WriteStartDocument()
$xmlWriter.WriteProcessingInstruction("xml-stylesheet", "type='text/xsl' href='style.xsl'")

# Start the Root Element
$xmlWriter.WriteStartElement("Root")
  
    $xmlWriter.WriteStartElement("Object") # <-- Start <Object>

        $xmlWriter.WriteElementString("Property1","Value 1")
        $xmlWriter.WriteElementString("Property2","Value 2")

        $xmlWriter.WriteStartElement("SubObject") # <-- Start <SubObject> 
            $xmlWriter.WriteElementString("Property3","Value 3")
        $xmlWriter.WriteEndElement() # <-- End <SubObject>

    $xmlWriter.WriteEndElement() # <-- End <Object>

$xmlWriter.WriteEndElement() # <-- End <Root> 

# End, Finalize and close the XML Document
$xmlWriter.WriteEndDocument()
$xmlWriter.Flush()
$xmlWriter.Close()

<?xml-stylesheet type='text/xsl' href='style.xsl'?>
<Root>
    <Object>
        <Property1>Value 1</Property1>
        <Property2>Value 2</Property2>
        <SubObject>
            <Property3>Value 3</Property3>
