Overview

This class simply represents an attribute within an XML document, and provides numerous properties and methods for deriving information about the attribute. It can also be used to set the attribute as a reference point for navigation or to alter the XML document structure.

Example (VB.NET): How to create an XMLAttribute object, set the XMLAtrribute.Value property, and insert an XMLAttribute into and XML document.

In the example below, we create an XMLAttribute object which we initialize using the XMLDocument.CreateAttribute method. The value of "demo" is assigned using the SetAttributeNode method to the XMLAttribute.Value property, prior to it being inserted into the XML document's parent element.

Dim objDocument As New System.Xml.XmlDocument

Dim strValue As String

objDocument.LoadXml("<sampleElement1><sampleElement2>We are demonstrating XML.</sampleElement2></sampleElement1>")

strValue = "Before: " & objDocument.InnerXml & CrLf & CrLf

Dim objAttribute As System.Xml.XmlAttribute

objAttribute = objDocument.CreateAttribute("category")

objAttribute.Value = "demo"

objDocument.DocumentElement.SetAttributeNode(objAttribute)

strValue &= "After: " & objDocument.InnerXml

TextBox1.Text = strValue
