(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>

Chilkat .NET Downloads Chilkat .NET Assemblies

Add-Type -Path "C:\chilkat\ChilkatDotNet47-9.5.0-x64\ChilkatDotNet47.dll"

$xml = New-Object Chilkat.Xml

$success = $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".
$success = $xml.UpdateAttribute("b","pear")

# Because no attribute named "c" exists, UpdateAttribute
# will create it:
$success = $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())
