Как видите, под узлами-родителями есть другие элементы, но я не забочусь об этом и хочу видеть только первый.
Я использую этот код для вызова шаблона со строкой нужных элементов в качестве параметра
и шаблон для цикла через строковый параметр, разделенный звездочкой: (title * url * notes *)

Единственный способ получить доступ к этому шаблону - использовать синтаксис // * [name () = $ first] для извлечения значения элемента на основе имени из параметра $ first.
Любая помощь очень ценится. Большое спасибо заранее. Не включая полный XML, поскольку есть тысячи строк ненужного текста.
