(PowerShell) Update an XML Attribute

Demonstrates how to update XML attributes.

The output XML is this:

<abc b="pear" c="orange" a="130">Test</abc>

Download: Chilkat .NET Assemblies

[Reflection.Assembly]::LoadFile("C:\myAssemblies\ChilkatDotNet2.dll")

$xml = New-Object Chilkat.Xml

$xml.LoadXml("<abc a=\"123\" b=\"apple\">Test</abc>")

#  The UpdateAttribute and AddOrUpdateAttribute methods
#  are identical.  Both will replace the attribute's value if it
#  already exists, or insert a new attribute if it does not yet exist.

#  Change the value of attribute "b" to "pear".
$xml.UpdateAttribute("b","pear")

#  Because no attribute named "c" exists, UpdateAttribute
#  will create it:
$xml.UpdateAttribute("c","orange")

#  If an attribute's value is an integer, the AddToAttribute
#  method may be called to update it by adding an integer value.
#  For example, update the value of "a" to "130" by adding 7.
$xml.AddToAttribute("a",7)

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