serialized をムリヤリ読んでも、バイナリだから意味不明だった。

xpath: /libraryDescription/searchConnectorDescriptionList/searchConnectorDescription[*]/simpleLocation/serialized

serialized: This element contains the base64-encoded ShellLink pointing to the location defined in the <url> element. Windows 7 creates the ShellLink from the value of the <url> element and properly updates this field on the first load of this library, so it should be left empty by the author.

PowerShell で XML

問題

なにも返ってこないぞ…

解決

Even a "default" namespace has to be specified

-Namespace

$ns = @{lib = 'http://schemas.microsoft.com/windows/2009/library'}
Select-Xml -Namespace $ns -XPath '//lib:libraryDescription'

完成

$ns = @{lib = 'http://schemas.microsoft.com/windows/2009/library'};
ls .\Books.library-ms |
  Select-Xml -Namespace $ns -XPath '//lib:url' |
  ls -LiteralPath { $_.Node.InnerText } -File -Recurse |
  where -not IsReadOnly |
  Set-ItemProperty -Name IsReadOnly -Value $true
