    </Continents>
    </World>

Я хочу перечислить описание для следующего условия -

 Country="India" OR City="New York"
 Continent="Asia" OR Country="Japan"

Answer 1

Попробуйте следующее:

//Description[
  (preceding-sibling::Cities[1]/Country = "India" or 
   preceding-sibling::Cities[1]/City = "New York"
  ) or 
  (preceding-sibling::Continent[1] = "Asia" or 
   preceding-sibling::Cities[1]/Country = "Japan"
  )
]

Вывод в моем тесте (--NODE-- - это текст, добавленный моим инструментом):

<Description>Newyork is a nice city</Description>-- NODE --
<Description>Mumbai is a nice city</Description>-- NODE --
<Description>New Delhi is a nice city</Description>-- NODE --
<Description>Kolkata is a nice city</Description>-- NODE --
<Description>Tokyo is a nice city</Description>
