	string target,
	string data
)
public XmlProcessingInstruction CreateProcessingInstruction (
	String target, 
	String data
)
public function CreateProcessingInstruction (
	target : String, 
	data : String
) : XmlProcessingInstruction
Not applicable.

Parameters

target

The name of the processing instruction.

data

The data for the processing instruction.

Return Value

The new XmlProcessingInstruction.

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.

using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main()
  {
    XmlDocument doc = new XmlDocument();

    // Create a procesing instruction.
    XmlProcessingInstruction newPI;
    String PItext = "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);

  }
}

import System.*;
import System.IO.*;
import System.Xml.*;

public class Sample
{
    public static void main(String[] args)
    {
        XmlDocument doc = new XmlDocument();

        // Create a procesing instruction.
        XmlProcessingInstruction newPI;
        String pIText = "type='text/xsl' href='book.xsl'";
        newPI = doc.CreateProcessingInstruction("xml-stylesheet", pIText);

        // Display the target and data information.
        Console.WriteLine("<?{0} {1}?>", newPI.get_Target(), newPI.get_Data());

        // Add the processing instruction node to the document.
        doc.AppendChild(newPI);
    } //main
