Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public virtual XmlNode CreateNode(
	XmlNodeType type,
	string prefix,
	string name,
	string namespaceURI
)

Parameters

type
Type: System.Xml.XmlNodeType

The XmlNodeType of the new node.

prefix
Type: System.String

The prefix of the new node.

name
Type: System.String

The local name of the new node.

namespaceURI
Type: System.String

The namespace URI of the new node.

Return Value

Type: System.Xml.XmlNode
The new XmlNode.

ExceptionCondition

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.

The following table shows you what NodeType[row] is allowed inside another NodeType[column] according to the W3C Extensible Markup Language (XML) 1.0 recommendation (www.w3.org/TR/1998/REC-xml-19980210).

* The XmlDeclaration node must be the first child of the Document node.

** Markup includes ProcessingInstruction and Comment nodes.

*** Element and CDATA nodes are only allowed in EntityReference nodes when the EntityReference node is not a child of an Attribute node.

**** Attributes are not children of an Element node. Attributes are contained inside an attribute collection that belongs to the Element node.

This method is a Microsoft extension to the Document Object Model (DOM).

The following example adds a new element to the document.

using System;
using System.Xml;

public class Sample {

  public static void Main() {

       XmlDocument doc = new XmlDocument();
       doc.LoadXml("<book>" +
                   "  <title>Oberon's Legacy</title>" +
                   "  <price>5.95</price>" +
                   "</book>"); 

       // Create a new element node.
       XmlNode newElem;
       newElem = doc.CreateNode(XmlNodeType.Element, "pages", "");  
       newElem.InnerText = "290";

       Console.WriteLine("Add the new element to the document...");
       XmlElement root = doc.DocumentElement;
       root.AppendChild(newElem);

       Console.WriteLine("Display the modified XML document...");
       Console.WriteLine(doc.OuterXml);
   }
 }
#using <mscorlib.dll>
#using <System.Xml.dll>
using namespace System;
using namespace System::Xml;

int main() 
{
       XmlDocument* doc = new XmlDocument();
       doc->LoadXml(S"<book>  <title>Oberon's Legacy</title>  <price>5.95</price></book>"); 

       // Create a new element node.
       XmlNode* newElem;
       newElem = doc->CreateNode(XmlNodeType::Element, S"pages", S"");  
       newElem->InnerText = S"290";

       Console::WriteLine(S"Add the new element to the document...");
       XmlElement* root = doc->DocumentElement;
       root->AppendChild(newElem);

       Console::WriteLine(S"Display the modified XML document...");
       Console::WriteLine(doc->OuterXml);
}
