    </xyz>
</abc>

The output XML is this:

<abc a="123">

$xml = New-Object Chilkat.Xml

$success = $xml.LoadXmlFile("add_attribute.xml")
if ($success -ne $true) {
    $($xml.LastErrorText)
    exit
}

#  Add an attribute  a="123" to the root node:
$xml.AddAttribute("a","123")

#  Navigate to the 1st child.  After calling FirstChild2,
#  "xml" now references the node with the tag "xyz".
$xml.FirstChild2()
$xml.AddAttribute("b","456")

#  Navigate to xyz's first child, which is the node having the
#  tag "mmm".
$xml.FirstChild2()
$xml.AddAttribute("c","789")
$xml.AddAttribute("d","000")

#  Revert back to the XML document root node
$xml.GetRoot2()

#  Examine the result:
$($xml.GetXml())
