类似语法如下：
"/bookstore/book[position()<count(/bookstore/book)]/price"
"/bookstore/book[position()<count(/bookstore/book)-1]/price"
"/bookstore/book[position()<count(/bookstore/book)-1]/price"
"/bookstore/book[position()<count(/bookstore/book)-sum(/bookstore/book/year)]/price"
2. What did you expect to see（期望看到什么）?
