A path selection never changes the nodes it is selecting.
You can go

doc("book.xml")//bookstore[book [price > 12]]

which selects all bookstore elements with a book > 12, howver
the children of $j will be as they were before, both books.

If you want to return a bookstore node with just books > 12, then you
will have to create a new element node, something like

doc("book.xml")//bookstore[book [price > 12]]/<bookstore>{book [price > 12]}</bookstore>
