createNode Method
Creates a node using the supplied type, name, and namespace.
Script Syntax
var objXMLDOMNode = oXMLDOMDocument.createNode(Type, name, namespaceURI);
Parameters
- Type
- A variant. A value that uniquely identifies the node type. This can be specified using either the integer value or the string value. For the complete list of values, see XML DOM Enumerated Constants or the description for the
name
parameter. - name
- A string containing the value for the new node's
nodeName
property. The relationship between thename
andType
parameters is summarized in the Remarks section of this topic. - namespaceURI
- A string defining the namespace URI. If specified, the node is created in the context of the
namespaceURI
parameter with the prefix specified on the node name. If thename
parameter does not have a prefix, this is treated as the default namespace.
Return Value
Object. Returns the newly created node.
Example
The following script example creates an attribute node called Sci-Fi
and adds it to the attributes for the DOMDocument
object.
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0"); var MyNode; var namedNodeMap; xmlDoc.async = false; xmlDoc.load("books.xml"); MyNode = xmlDoc.createNode(2, "Sci-Fi", ""); namedNodeMap = xmlDoc.documentElement.childNodes.item(0).attributes; namedNodeMap.setNamedItem(MyNode); alert(xmlDoc.documentElement.xml);
Visual Basic Syntax
Set objXMLDOMNode = oXMLDOMDocument.createNode(Type, name, namespaceURI)
Parameters
- Type
- A variant. A value that uniquely identifies the node type. This can be specified using either the integer value or the string value. For the complete list of values, see the XML DOM Enumerated Constants or the description for the
name
parameter. - name
- A string containing the value for the new node's
nodeName
property. The relationship between thename
andType
parameters is summarized in the Remarks section of this topic. - namespaceURI
- A string defining the namespace URI. If specified, the node is created in the context of the
namespaceURI
parameter with the prefix specified on the node name. If thename
parameter does not have a prefix, this is treated as the default namespace.
Return Value
An object. Returns the newly created node.
Example
The following Microsoft® Visual Basic® example creates an attribute node called Sci-Fi
and adds it to the attributes for the DOMDocument
object.
Dim xmlDoc As New Msxml2.DOMDocument50 Dim MyNode As IXMLDOMNode Dim namedNodeMap As IXMLDOMNamedNodeMap xmlDoc.async = False xmlDoc.Load ("books.xml") If (xmlDoc.parseError.errorCode <> 0) Then Dim myErr Set myErr = xmlDoc.parseError MsgBox("You have error " & myErr.reason) Else Set MyNode = xmlDoc.createNode(NODE_ATTRIBUTE, "Sci-Fi", "") Set namedNodeMap = xmlDoc.documentElement.childNodes.Item(0).Attributes namedNodeMap.setNamedItem MyNode MsgBox (xmlDoc.documentElement.xml) End If
C/C++ Syntax
HRESULT createNode( VARIANT Type, BSTR name, BSTR namespaceURI, IXMLDOMNode **node);
Parameters
- Type [in]
- The value that uniquely identifies the node type. This can be specified using either the integer value or the string value. For the complete list of values, see the XML DOM Enumerated Constants or the description given for the
name
parameter. - name [in]
- The value for the new node's
nodeName
property. The relationship between thename
andType
parameters is summarized in the Remarks section of this topic. - namespaceURI [in]
- The namespace URI. If specified, the node is created in the context of the
namespaceURI
parameter with the prefix specified on the node name. If thename
parameter does not have a prefix, this is treated as the default namespace. - node [out, retval]
- The newly created node.
C/C++ Return Values
- S_OK
- The value returned if successful.
- E_INVALIDARG
- The value returned if the
node
parameter is Null. - E_FAIL
- The value returned if an error occurs.
Remarks
The name
parameter depends on the value of the Type
parameter:
NODE_ATTRIBUTE |
The name of the attribute. |
NODE_CDATA_SECTION , NODE_COMMENT , NODE_DOCUMENT , NODE_DOCUMENT_FRAGMENT , NODE_TEXT |
The nodeName property for these node types is a constant value; the name parameter is ignored. |
NODE_DOCUMENT_TYPE |
The name of the document type; for example, the xxx in <!DOCTYPE xxx ...> . |
NODE_ELEMENT |
The name of the XML tag, with any namespace prefix included if present. |
NODE_ENTITY |
The name of the entity. |
NODE_ENTITY_REFERENCE |
The name of the entity referenced. The name does not include the leading ampersand or the trailing semicolon. The name includes the namespace, if one is present. |
NODE_NOTATION |
The name of the notation. |
NODE_PROCESSING_INSTRUCTION |
The target, the first token following the <? characters. |
You cannot create a node of type NODE_DOCUMENT
, NODE_DOCUMENT_TYPE
, NODE_ENTITY
, or NODE_NOTATION
.
When a node is created, it is created in the context of a namespace if one is supplied (if the namespaceURI
parameter is supplied). If one is not supplied, the node is created in the namespace of the document. If the namespaceURI
parameter is specified, the node is created in the context of the namespaceURI
parameter with the prefix specified on the node name.
For node types that do not have names, the empty string, "", should be passed as the name
parameter.
For elements and entity references, when the value of the namespaceURI
parameter is anything other than "", and the value of the name
parameter does not contain a prefix (xxx in xxx:yyy), the value of the namespaceURI
parameter is treated as the default namespace.
Attributes cannot be scoped to a default namespace, and other elements are not qualified to a particular namespace; they are treated as being from the namespace defined by the document itself.
When the value of namespaceURI
parameter is the empty string, "", the node is created without a namespace. Creating a qualified node without specifying a nonempty namespaceURI
returns an error. This member is an extension of the Worldwide Web Consortium (W3C) Document Object Model (DOM).
