XElement.Attributes Method (XName)

Returns a filtered collection of attributes of this element. Only elements that have a matching XName are included in the collection.

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

public IEnumerable<XAttribute> Attributes(
	XName name
)

Parameters

name
Type: System.Xml.Linq.XName
The XName to match.

Return Value

Type: System.Collections.Generic.IEnumerable<XAttribute>
An IEnumerable<T> of XAttribute that contains the attributes of this element. Only elements that have a matching XName are included in the collection.

Attribute names must be unique within an element. Therefore, this axis method can return either a collection that contains only one attribute, or it can return an empty collection.

This method uses deferred execution.

The following example uses this axis method.

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

This example produces the following output:

Att1="content1"

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 + "Att1", "content1"),
    new XAttribute(aw + "Att2", "content2")
);
IEnumerable<XAttribute> attList = xmlTree.Attributes(aw + "Att1");
foreach (XAttribute att in attList)
    Console.WriteLine(att);

This example produces the following output:

aw:Att1="content1"
