createNode Method

  • 项目

Creates a node using the supplied type, name, and namespace.

var objXMLDOMNode = oXMLDOMDocument.createNode(Type, name, namespaceURI);

HRESULT createNode(
  VARIANT Type,
  BSTR name,
  BSTR namespaceURI,
  IXMLDOMNode** node
);

General Remarks

The name parameter depends on the value of the type parameter:

Value Description
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. Note that 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 namespaceURI is specified, the node is created in the context of the namespaceURI 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 namespaceURI parameter is anything other than "" and the name parameter does not contain a prefix (xxx in xxx:yyy), the namespaceURI 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 namespaceURI is the empty string, "", the node is created within the special namespace of the current document. Creating a qualified node without specifying a nonempty namespaceURI returns an error. This member is an extension of the World Wide Web Consortium (W3C) Document Object Model (DOM).

This method applies to the following interface:

DOMDocument.
