Although this method creates the new object in the context of the document, it does not automatically add the new object to the document tree. To add the new object, you must explicitly call one of the node insert methods.
According to the W3C Extensible Markup Language (XML) 1.0 recommendation (www.w3.org/TR/1998/REC-xml-19980210), ProcessingInstruction nodes are only allowed within Document, Element, and EntityReference nodes, when the EntityReference node is not a child of an Attribute node.
The following example creates a ProcessingInstruction node and adds it to the document.
Imports System Imports System.IO Imports System.Xml public class Sample public shared sub Main() Dim doc as XmlDocument = new XmlDocument() ' Create a procesing instruction. Dim newPI as XmlProcessingInstruction Dim PItext as String = "type='text/xsl' href='book.xsl'" newPI = doc.CreateProcessingInstruction("xml-stylesheet", PItext) ' Display the target and data information. Console.WriteLine("<?{0} {1}?>", newPI.Target, newPI.Data) ' Add the processing instruction node to the document. doc.AppendChild(newPI) end sub end class
