Теперь нам нужно сгруппировать активы по первому атрибуту Type (бывший глобализации), а затем необходимо сгруппировать по значению (бывшая Страна stratagies). Нам нужно отображать глобализацию и стратарии только один раз и нужно отображать все активы ниже этого. Я могу сделать это с XSLT 2.0 легко, но он не поддерживается в Microsoft .net, поэтому он не может использовать.

Может ли кто-нибудь помочь мне здесь?

Заранее спасибо.
