That provides
the flexibility to use LINQ to XML to enumerate the results and write them to an XmlWriter, as shown in
the highlighted code.
IEnumerable xmlTree =
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")),
new XElement("OrderDate", el.Attribute("Date"))
)
);
XmlWriterSettings xws = new XmlWriterSettings();
xws.OmitXmlDeclaration = true;
xws.Indent = true;
using (XmlWriter xw = XmlWriter.Create(@"c:\Wrox\output.xml", xws))
{
xw.WriteStartElement("Root");

foreach (XElement el in xmlTree)
el.WriteTo(xw);
xw.WriteEndElement();
}
You should get the same results as the previous example.
Summary
On the surface, LINQ to XML looks intimidating, but this and the previous three chapters should have
dispelled that vicious rumor.
