    how to write the follow XmlPath 1.0:

    1) return all the books provided all the book’s prices are not equal 14.95 ?

    /inventory/book[price/text() != 14.95]

    “/inventory/book” gives you all the children elements named “books” of the “inventory” Node. and “price/text() != 14.95” simply means for each book, check whether one their child element named “price” is different than 14.95. instead of “/inventory/book”, you can rather use “//book” for the convenience of your application. “//book” ask for all descendant elements named “book” from your current node (in this case the root element)

    2) return all the books that thier price is bigger then the price of the book after them .

    /inventory/book[price >  following-sibling::book[position() = 1]/price]
