This class represents an XML element, the fundamental XML construct.
An element has an XName, optionally one or more attributes, and can optionally contain content (for more information, see Nodes).
An XElement can contain the following types of content:
For details about the valid content of an XElement, see Valid Content of XElement and XDocument Objects.
XElement derives from XContainer, which derives from XNode.
Some XElement methods can be used from XAML. For more information, see LINQ to XML Dynamic Properties.
The following example creates an XML tree. The content of the new element comes from a LINQ query.
XElement xmlTree1 = new XElement("Root",
new XElement("Child1", 1),
new XElement("Child2", 2),
new XElement("Child3", 3),
new XElement("Child4", 4),
new XElement("Child5", 5),
new XElement("Child6", 6)
);
XElement xmlTree2 = new XElement("Root",
from el in xmlTree1.Elements()
where((int)el >= 3 && (int)el <= 5)
select el
);
Console.WriteLine(xmlTree2);
Dim xmlTree1 As XElement = _
<Root>
<Child1>1</Child1>
<Child2>2</Child2>
<Child3>3</Child3>
<Child4>4</Child4>
<Child5>5</Child5>
<Child6>6</Child6>
</Root>
Dim xmlTree2 As XElement = _
<Root>
<%= From el In xmlTree1.Elements() _
Where el.Value >= 3 And el.Value <= 5 _
Select el %>
</Root>
Console.WriteLine(xmlTree2)
This example produces the following output:
<Root>
<Child3>3</Child3>
<Child4>4</Child4>
<Child5>5</Child5>
</Root>
The following is the same example, but in this case the XML is in a namespace. For more information, see Working with XML Namespaces.
XNamespace aw = "http://www.adventure-works.com";
XElement xmlTree1 = new XElement(aw + "Root",
new XElement(aw + "Child1", 1),
new XElement(aw + "Child2", 2),
new XElement(aw + "Child3", 3),
new XElement(aw + "Child4", 4),
new XElement(aw + "Child5", 5),
new XElement(aw + "Child6", 6)
);
XElement xmlTree2 = new XElement(aw + "Root",
from el in xmlTree1.Elements()
where((int)el >= 3 && (int)el <= 5)
select el
);
Console.WriteLine(xmlTree2);

This example produces the following output:
<Root xmlns="http://www.adventure-works.com">
<Child3>3</Child3>
<Child4>4</Child4>
<Child5>5</Child5>
</Root>
