XElement.Attributes Method

.NET Framework 4

Other Versions

Returns a collection of attributes of this element.

Namespace: System.Xml.Linq
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)

Syntax

C++

Copy

public IEnumerable<XAttribute> Attributes()

Return Value

Type: System.Collections.Generic.IEnumerable<XAttribute>
An IEnumerable<T> of XAttribute of attributes of this element.

Remarks

The attributes in the returned collection are in the order that they were added to the element. If the XML tree was parsed from XML, the attributes are returned in document order.

This method uses deferred execution.

Examples

The following example creates an element with two attributes. It then uses this axis method to retrieve all attributes of the element.

Copy

XElement xmlTree = new XElement("Root",
    new XAttribute("Att1", "content1"),
    new XAttribute("Att2", "content2")
);
IEnumerable<XAttribute> attList =
    from at in xmlTree.Attributes()
    select at;
foreach (XAttribute att in attList)
    Console.WriteLine(att);

This example produces the following output:

Copy

Att1="content1"
Att2="content2"

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

Copy

XNamespace aw = "http://www.adventure-works.com";
XElement xmlTree = new XElement(aw + "Root",
    new XAttribute(aw + "Att1", "content1"),
    new XAttribute(aw + "Att2", "content2"),
    new XAttribute(XNamespace.Xmlns + "aw", "http://www.adventure-works.com")
);
IEnumerable<XAttribute> attList =
    from at in xmlTree.Attributes()
    select at;
foreach (XAttribute att in attList)
    Console.WriteLine(att);

This example produces the following output:

Copy

aw:Att1="content1"
aw:Att2="content2"
xmlns:aw="http://www.adventure-works.com"
