Returns the XAttribute of this XElement that has the specified XName.

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

Public Function Attribute (
	name As XName
) As XAttribute


Type: System.Xml.Linq.XName

The XName of the XAttribute to get.

Return Value

Type: System.Xml.Linq.XAttribute

An XAttribute that has the specified XName; null if there is no attribute with the specified name.

Some return collections of elements or attributes. This method returns only a single attribute. Sometimes this is referred to as a singleton (in contrast to a collection).

Visual Basic users can use the integrated attribute axis to retrieve the value of an attribute with a specified name.

The following example creates an element with an attribute. It then retrieves the attribute using this method.

                Dim xmlTree As XElement = <Root Att="attribute content"/>

Dim att As XAttribute = xmlTree.Attribute("Att")

This example produces the following output:

Att="attribute content"

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

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

Module Module1
    Sub Main()
        Dim xmlTree As XElement = <aw:Root aw:Att="attribute content"/>

        Dim att As XAttribute = xmlTree.Attribute(GetXmlNamespace(aw) + "Att")
    End Sub
End Module

This example produces the following output:

aw:Att="attribute content"
