Нужна помощь в обновлении (windows unattend.xml) XML-файла с powershell

Question

Вот мой XML-файл: я бы предпочел прочитать xml, а затем изменить имя компьютера, указав newcompname и записать его обратно в файл

Answer 1

Вы можете использовать различные методы, итерируя по узлам, как в следующем примере, вызывая select-xml с запросом XPATH, чтобы найти узел и затем изменить значение, или $ xml.selectNodes (...).Обычно я бы пошел по пути xpath, но с включенным пространством имен и простым XML это был самый простой способ продемонстрировать это в PowerShell

$xml = [xml]@"
