createNode Method
Creates a node using the supplied type, name, and namespace.
JScript 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 the name and Type 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 the name 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.6.0");
var MyNode;
var namedNodeMap;
xmlDoc.async = false;
xmlDoc.loadXML("<root><child/></root>");
MyNode = xmlDoc.createNode(2, "Sci-Fi", "");
namedNodeMap = xmlDoc.documentElement.childNodes.item(0).attributes;
namedNodeMap.setNamedItem(MyNode);
WScript.Echo(xmlDoc.documentElement.xml);
Output
<root><child Sci-Fi=""/></root>
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 the name and Type 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 the name parameter does not have a prefix, this is treated as the default namespace.
node[out, retval]
The newly created node.
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).
