XContainer.Elements Method

Returns a collection of the child elements of this element or document, in document order.

Namespace:  System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)
public IEnumerable<XElement> Elements()

Return Value

Type: System.Collections.Generic.IEnumerable<XElement>
An IEnumerable<T> of XElement containing the child elements of this XContainer, in document order.

This method uses deferred execution.

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);

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 Working 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);

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>
