Overview

The XmlNodeReader class is a specialized implementation of the XmlReader class that allows you to read information about an XmlNode. Note that the XmlNodeReader is a forward-only reader which does not perform any validation.

Example (VB.NET): How to read a list of attributes from an element node using the XmlNodeReader.MoveToContent and XmlNodeReader.MoveToAttribute methods.

In the following example we create an XmlNodeReader object and assign it an XmlDocument with one element. We read in the element's attributes by first ensuring the element has attributes (using the XmlNodeReader.HasAttributes property), and then by looping through the number of available attributes identified by the XmlNodeReader.AttributeCount value.

Dim objDocument As New System.Xml.XmlDocument

Dim objXmlNodeReader As System.Xml.XmlNodeReader

Dim strValues As String

Dim x As Integer

objDocument.LoadXml("<sampleElement phrase='Everybody' phrase1='say' phrase3='hey' phrase4='!'>Test Value</sampleElement>")

objXmlNodeReader = New XmlNodeReader(objDocument)

objXmlNodeReader.MoveToContent()

If objXmlNodeReader.HasAttributes Then

For x = 0 To objXmlNodeReader.AttributeCount - 1

objXmlNodeReader.MoveToAttribute(x)

strValues &= objXmlNodeReader.Value & " "

Next x
