XmlAttribute Class

Namespace: System.Xml
Assembly: System.Xml.dll

Represents an attribute of an element in the XML document object model (DOM).

Syntax

public class XmlAttribute : XmlNode

Inheritance

Object → XmlNode → XmlAttribute

Remarks

An XmlAttribute node is a child of an XmlElement node. It stores name/value pairs for an element. The Value property returns the concatenated values of all descendant text nodes. If the attribute has no text nodes, it returns an empty string. If the attribute has text nodes and other node types, it returns the concatenated string values of the text nodes.

The XmlAttribute class provides properties to access the attribute's name, value, and the element it belongs to. You can create and manipulate attributes using methods of the XmlDocument class, such as CreateAttribute and SetAttribute.

Examples

Creating and Appending an Attribute

XmlDocument doc = new XmlDocument();
doc.LoadXml("<root></root>");

// Create an attribute
XmlAttribute attr = doc.CreateAttribute("myAttribute");
attr.Value = "attributeValue";

// Append the attribute to the root element
doc.DocumentElement.Attributes.Append(attr);

Console.WriteLine(doc.OuterXml);
// Output: <root myAttribute="attributeValue"></root>
