  To get all book elements with ID = 100, use XPathDocument:

  XPathDocument xPathDocument = new XPathDocument("Data.xml");
        XPathNavigator xPathNavigator = xPathDocument.CreateNavigator();
        XPathNodeIterator books = xPathNavigator.Select("/books/book[./id = '100']");
        while (books.MoveNext()) {
          string book = books.Current.OuterXml;
        }
