How to: Sort Elements
This example shows how to write a query that sorts its results.
Example
This example uses the following XML document: Sample XML File: Numerical Data (LINQ to XML).
XElement root = XElement.Load("Data.xml");
IEnumerable<decimal> prices =
from el in root.Elements("Data")
let price = (decimal)el.Element("Price")
orderby price
select price;
foreach (decimal el in prices)
Console.WriteLine(el);
Dim root As XElement = XElement.Load("Data.xml")
Dim prices As IEnumerable(Of Decimal) = _
From el In root.<Data> _
Let price = Convert.ToDecimal(el.<Price>.Value) _
Order By (price) _
Select price
For Each el As Decimal In prices
Console.WriteLine(el)
Next
This code produces the following output:
0.99
4.95
6.99
24.50
29.00
66.00
89.99
The following example shows the same query for XML that is in a namespace. For more information, see Working with XML Namespaces.
This example uses the following XML document: Sample XML File: Numerical Data in a Namespace.
XElement root = XElement.Load("DataInNamespace.xml");
XNamespace aw = "http://www.adatum.com";
IEnumerable<decimal> prices =
from el in root.Elements(aw + "Data")
let price = (decimal)el.Element(aw + "Price")
orderby price
select price;
foreach (decimal el in prices)
Console.WriteLine(el);
Imports <xmlns='http://www.adatum.com'>
Module Module1
Sub Main()
Dim root As XElement = XElement.Load("DataInNamespace.xml")
Dim prices As IEnumerable(Of Decimal) = _
From el In root.<Data> _
Let price = Convert.ToDecimal(el.<Price>.Value) _
Order By (price) _
Select price
For Each el As Decimal In prices
Console.WriteLine(el)
Next
End Sub
End Module
This code produces the following output:
0.99
4.95
6.99
24.50
29.00
66.00
89.99
