Return Value
Type: System.Xml.Linq.XAttributeAn XAttribute that has the specified XName; null if there is no attribute with the specified name.
Some axis methods 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.
XElement xmlTree = new XElement("Root", new XAttribute("Att", "attribute content") ); XAttribute att = xmlTree.Attribute("Att"); Console.WriteLine(att);
Dim xmlTree As XElement = <Root Att="attribute content"/> Dim att As XAttribute = xmlTree.Attribute("Att") Console.WriteLine(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.
XNamespace aw = "http://www.adventure-works.com"; XElement xmlTree = new XElement(aw + "Root", new XAttribute(XNamespace.Xmlns + "aw", "http://www.adventure-works.com"), new XAttribute(aw + "Att", "attribute content") ); XAttribute att = xmlTree.Attribute(aw + "Att"); Console.WriteLine(att);
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") Console.WriteLine(att) End Sub End Module
This example produces the following output:
aw:Att="attribute content"
