Not too bad. The next example utilizes the date attribute on the XML document to build the XML fragment.
Modify the code in your Visual Studio application as follows:
DateTime startDate;
DateTime endDate;
DateTime.TryParse("02/01/2007", out startDate);
DateTime.TryParse("02/28/2007", out endDate);
XElement xmlTree = new XElement("Sales",
from el in StreamSalesOrders(@"C:\Wrox\LINQ\Chapter 8\Orders.xml")
where (DateTime)el.Attribute("Date") >= startDate
&& (DateTime)el.Attribute("Date") <= endDate
select new XElement("Order",
new XElement("SalesPerson",
(string)el.Parent.Element("Name")),
new XElement(el.Element("Amount"))
)
);
This example uses the date attribute of each order to filter the information. Based on this criterion, the
following results are produced:


Scott
9.00


Steve
999.00


One more modification: the following example takes the order date attribute and adds it to the resulting
XML tree as an element.
