public:
 System::Collections::Generic::IEnumerable<System::Xml::Linq::XElement ^> ^ Elements();

public System.Collections.Generic.IEnumerable<System.Xml.Linq.XElement> Elements();

member this.Elements : unit -> seq<System.Xml.Linq.XElement>

Public Function Elements () As IEnumerable(Of XElement)

Returns

An IEnumerable<T> of XElement containing the child elements of this XContainer, in document order.

Examples

The following example creates an XML tree, and then selects some elements using this axis method.

XElement xmlTree = new XElement("Root",
 new XElement("Child1", 1),
 new XElement("Child2", 2),
 new XElement("Child3", 3),
 new XElement("Child4", 4),
 new XElement("Child5", 5)
);
IEnumerable<XElement> elements =
 from el in xmlTree.Elements()
 where (int)el <= 3
 select el;
foreach (XElement el in elements)
 Console.WriteLine(el);

Dim xmlTree As XElement = _
 <Root>
 <Child1>1</Child1>
 <Child2>2</Child2>
 <Child3>3</Child3>
 <Child4>4</Child4>
 <Child5>5</Child5>
 </Root>

Dim elements = From el In xmlTree.Elements _
 Where el.Value <= 3 _
 Select el

For Each el In elements
 Console.WriteLine(el)
Next

This example produces the following output:

<Child1>1</Child1>
<Child2>2</Child2>
<Child3>3</Child3>

The following is the same example, but in this case the XML is in a namespace. For more information, see Work with XML Namespaces.

XNamespace aw = "http://www.adventure-works.com";
XElement xmlTree = new XElement(aw + "Root",
 new XAttribute(XNamespace.Xmlns + "aw", "http://www.adventure-works.com"),
 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)
);
IEnumerable<XElement> elements =
 from el in xmlTree.Elements()
 where (int)el <= 3
 select el;
foreach (XElement el in elements)
 Console.WriteLine(el);

Imports <xmlns:aw="http://www.adventure-works.com">

Module Module1
 Sub Main()
 Dim xmlTree As XElement = _
 <aw:Root>
 <aw:Child1>1</aw:Child1>
 <aw:Child2>2</aw:Child2>
 <aw:Child3>3</aw:Child3>
 <aw:Child4>4</aw:Child4>
 <aw:Child5>5</aw:Child5>
 </aw:Root>

 Dim elements = From el In xmlTree.Elements _
 Where el.Value <= 3 _
 Select el

 For Each el In elements
 Console.WriteLine(el)
 Next
 End Sub
End Module

This example produces the following output:

<aw:Child1 xmlns:aw="http://www.adventure-works.com">1</aw:Child1>
<aw:Child2 xmlns:aw="http://www.adventure-works.com">2</aw:Child2>
<aw:Child3 xmlns:aw="http://www.adventure-works.com">3</aw:Child3>

Remarks

This method uses deferred execution.

member this.Elements : System.Xml.Linq.XName -> seq<System.Xml.Linq.XElement>

Public Function Elements (name As XName) As IEnumerable(Of XElement)

Parameters

Returns

An IEnumerable<T> of XElement containing the children of the XContainer that have a matching XName, in document order.

Examples

The following example creates an XML tree, and then selects several child elements using this axis method.

XElement xmlTree = new XElement("Root",
 new XElement("Type1", 1),
 new XElement("Type1", 2),
 new XElement("Type2", 3),
 new XElement("Type2", 4),
 new XElement("Type2", 5)
);
IEnumerable<XElement> elements =
 from el in xmlTree.Elements("Type2")
 select el;
foreach (XElement el in elements)
 Console.WriteLine(el);

Dim xmlTree As XElement = _
 <Root>
 <Type1>1</Type1>
 <Type1>2</Type1>
 <Type2>3</Type2>
 <Type2>4</Type2>
 <Type2>5</Type2>
 </Root>

Dim elements = From el In xmlTree.<Type2> _
 Select el

For Each el In elements
 Console.WriteLine(el)
Next

This example produces the following output:

<Type2>3</Type2>
<Type2>4</Type2>
<Type2>5</Type2>

The following is the same example, but in this case the XML is in a namespace. For more information, see Work with XML Namespaces.

XNamespace aw = "http://www.adventure-works.com";
XElement xmlTree = new XElement(aw + "Root",

 new XElement(aw + "Type1", 1),
 new XElement(aw + "Type1", 2),
 new XElement(aw + "Type2", 3),
 new XElement(aw + "Type2", 4),
 new XElement(aw + "Type2", 5)
);
IEnumerable<XElement> elements =
 from el in xmlTree.Elements(aw + "Type2")
 select el;
foreach (XElement el in elements)
 Console.WriteLine(el);
